Geant4 10.7-beta-01 Release Notes
|
|
---------------------------------
|
|
|
|
26 June 2020
|
|
|
|
Migration Notes & Main New Features
|
|
-----------------------------------
|
|
|
|
o Introducing new optional (experimental) tasking system, based on PTL
|
|
(Parallel Tasking Library), dedicated run manager (G4TaskRunManager) and
|
|
factory (G4RunManagerFactory), enabling use of tasks for the event loop.
|
|
The tasking system is fully compatible with Intel TBB, which can be
|
|
selected if GEANT4_USE_TBB=ON is specified when configuring CMake. The
|
|
default behavior is to submit the tasks to an internal thread-pool and
|
|
task-queue. A comprehensive description of the system and options available
|
|
can be found in the README document located within the new source/tasking
|
|
module.
|
|
o Revision of G4PhysicsVector classes to use similar algorithm for bin
|
|
selection and adding checks on vectors length.
|
|
o G4PhysicsLinearVector, G4PhysicsLogVector: more accurate checks in class
|
|
constructors.
|
|
o New class G4DriverReporter to print progress of field drivers.
|
|
o Enabled "check-mode" for G4PropagatorInField and G4VIntersectionLocator.
|
|
Enable use of whiteboard for logging/debugging in G4MultiLevelLocator, if
|
|
"check-mode" in navigation is being activated through UI command.
|
|
o Added layered mass geometry option for the new "probe" scoring mesh.
|
|
o Introducing G4VPrimitivePlotter allowing the user to extend a primitive
|
|
scorer and directly fill a 1D histogram.
|
|
o Enabled handling of automatic min/max axes values in case of log scale
|
|
in analysis tools.
|
|
o Fixed reading and writing of const properties of materials in GDML.
|
|
o Cleanup destruction of physics processes at the end of job.
|
|
Reviewed ownership/deletion of physics models at the end of the run.
|
|
o Introducing thermal model of positronium decay to two gammas.
|
|
In this model, the positronium acquires a mean kinetic energy on formation,
|
|
which contributes to a small non-collinearity of the gammas, detectable and
|
|
significant in PET.
|
|
o Added new EM model for polarized gamma elastic scattering.
|
|
o Implemented three time constants for G4Scintillation, and allow multiple
|
|
time constants to work with scintillation by particle type.
|
|
o Added second wavelength shifting process within the same material.
|
|
o New physics-list builder classes to allow alternative builders for
|
|
anti_proton, anti_neutron, hyperons and anti-hyperons nuclear interactions
|
|
at high energies with QGSP.
|
|
o Extended EM physics-list constructors to allow extra available DNA options.
|
|
o New General Particle Source energy distribution option that generates flat
|
|
energy distribution with track weights representing energy spectrum.
|
|
o Added handling of lepto-nuclear interactions for anti_nu_e, nu_e and
|
|
anti_mu_nu.
|
|
o Define PDG code as "-22" for G4OpticalPhoton.
|
|
o Added implementation of IRT in G4DNA module.
|
|
o Added new UI messenger for hadronic physics, currently used for controlling
|
|
verbosity level: the UI command "/process/had/verbose 0" allows to switch
|
|
off the print-out at initialization of hadronic processes, models and
|
|
cross sections (similar to the existing command "/process/em/verbose 0"
|
|
to switch off the print-out of electromagnetic physics information).
|
|
o Fixed non-conservation warnings coming from G4HadronicProcess due to
|
|
sub-threshold reactions in Bertini cascade.
|
|
o G4CrossSectionElastic, G4CrossSectionInelastic: fix of the max energy of
|
|
applicability of the (elastic and inelastic) cross-sections of ions and
|
|
anti-ions nuclear interactions.
|
|
o Improved treatment of antibaryon interactions in QGS.
|
|
o Added support for OpenInventor Qt visualisation driver to be built and
|
|
used in applications. The OpenInventor module can be built with either
|
|
the OIQT driver, or with the OIX/OIXE drivers, but not with both.
|
|
Enabled use of OIQT viewer with Qt UI.
|
|
o New advanced example showing how to efficiently simulate particle transport
|
|
through aerosols containing billions of randomly-positioned droplets, using
|
|
an ordinary workstation.
|
|
o Added support for modular builds in CMake.
|
|
o Extended CMake build system to support G4Py activation through
|
|
GEANT4_USE_PYTHON flag.
|
|
o Build option with VecGeom requires VecGeom-1.1.7.
|
|
o New data sets G4EMLOW-7.12.
|
|

|
|
----------------------------------------------------------------------------
|
|
|
|
List of features and fixes included in this Beta release since 10.6.p02:
|
|
|
|
o Configuration:
|
|
-------------
|
|
+ CMake:
|
|
o Added support for building PTL external module and introduced
|
|
GEANT4_USE_TBB option, enabling use of TBB as possible alternative
|
|
to builtin PTL tasking.
|
|
o Added support for OpenInventor Qt visualisation driver to be built and
|
|
used in applications. The OpenInventor module can be built with either
|
|
the OIQT driver, or with the OIX/OIXE drivers, but not with both.
|
|
Added GEANT4_USE_XM to OpenInventor X11 driver code block to correct
|
|
Xm and Xt link order.
|
|
o Removed requirement on presence of GLU library.
|
|
No longer save GLU related variables in the package cache.
|
|
o Change shimmed imported target name to VecGeom::vecgeom to match
|
|
upstream usage and reliably use target when available from VecGeom.
|
|
Export VecCore_DIR to package cache when set so that Geant4 behaviour
|
|
is consistent. Co-works with VecGeom-1.1.7.
|
|
o Added GEANT4_USE_NEW_CMAKE option in preparation for testing of modular
|
|
build updates, ON by default, to switch between systems. Importing new
|
|
"target" style API for declaring and composing libraries from modules
|
|
of source code. Retain GEANT4_BUILDTREE_INCLUDE_DIRS in new CMake
|
|
system to support clients that may not yet support CMake target usage
|
|
requirements.
|
|
o Propagate value of CMAKE_DISABLE_FIND_PACKAGE_ROOT down to tests
|
|
that optionally support Root to allow testing Geant4 with Root support
|
|
disabled. This is necessary when testing Geant4 with a different C++
|
|
standard than Root when it's installed. Avoid warnings from propagating
|
|
the flag down to tests.
|
|
o Applied patch to allow compilation on Windows using Clang.
|
|
o Use "${FOO:-}" variable expansion and "-z" test to check for
|
|
undefined variables in Bourne Shell scripts. Prevents errors when
|
|
shell is in "set -u" mode. Addressing problem report #2221.
|
|
o Handle install of G4clhep{-static} independently of main modules
|
|
due it being built outside the category system.
|
|
o Renamed remaining internal "Geant4..." modules to "G4" convention.
|
|
Retain Geant4DefineModule and Geant4LibraryTargets until new
|
|
modularization scheme is in place.
|
|
o Updated version of data sets: G4EMLOW-7.12.
|
|
Updated tag-IDs for 10.7-beta.
|
|
+ GNUMake:
|
|
o Added setup for building and configuring new externals/ptl
|
|
and tasking modules. External installation of PTL can be enabled
|
|
by defining the installation through the environment variable
|
|
PTL_BASE_DIR.
|
|
o Added -pthread to all builds in Linux targets.
|
|
o Corrected setup for use of OpenInventor (Coin).
|
|
o Added missing settings in G4UI_BUILD.gmk script for OIQt and use of UI.
|
|
o Removed deprecated G4USE_STD11 flag settings.
|
|
o Removed dependency on GLU for all configurations, as no longer
|
|
necessary.
|
|
|
|
o Analysis:
|
|
--------
|
|
+ Updated to g4tools 5.1.0:
|
|
o Corrections to handle automatic min/max axes values in case of log
|
|
scale. See History_tools in analysis module for all details.
|
|
+ Fix to add a null-pointer check to ntupleDescription->fNtuple in
|
|
G4RootPNtupleManager::Merge().
|
|
+ Fixed compilation warnings on clang-10 for g4tools.
|
|
+ Cleanup CMake build, removing obsolete granular library options and
|
|
explicit include_directories.
|
|
+ Update granular dependencies in preparation for modularization
|
|
+ Remove uneeded links to externals in factory.
|
|
|
|

|
|
-----------------
|
|
+ Cleanup CMake build, removing obsolete granular library options and
|
|
explicit include_directories.
|
|
|
|
o Event:
|
|
-----
|
|
+ Introducing a new General Particle Source energy distribution option,
|
|
that generates flat energy distribution with track weights that
|
|
represent energy spectrum provided by /gps/hist/point commands.
|
|
This option can enhance, for example, higher energy tracks that are
|
|
rare but contribute to the scores.
|
|

|
|
o G4MagInt_Driver: fixed max iterations & clarified that its method
|
|
ComputeNewStepSize() does not (yet) respect maximum reduction factor
|
|
(0.1); this is to enable comparisons with new G4IntegrationDriver<>
|
|
implementation.
|
|
o G4OldMagIntDriver maintains all old behaviour of G4MagInt_Driver.
|
|
o In G4MultiLevelLocator, added ability to record in a 'whiteboard',
|

|
|
o G4PropagationInField: improved ClearPropagatorState() method.
|
|
o Implemented move constructor and operator for G4FieldTrack.
|

|
|
if "check-mode" in navigation is being activated through UI command.
|
|
o Reordered data members in G4Navigator, to reduce object size.
|
|

|
|
|
|
o Global:
|
|
------

|
|
to 8; use similar algorithm for bin selection as in 1D vector;
|
|
if any dimension is less than 2 throw a G4Exception.
|
|
+ G4PhysicsVector: use same code for interpolation for all types of
|
|
PhysicsVector; removed obsolete unused methods; maximally use const
|
|
variables; preserve precision of printout.
|
|
+ G4PhysicsLinearVector: added checks on vector length: if it is less
|
|
than 2 throw a G4Exception.
|
|

|
|
than 3 throw a G4Exception.
|

|
|
code cleanup/formatting.
|
|
+ Removed use of deprecated G4USE_STD11 flag.
|
|
+ Fix to CMake script to support new CMake system.
|
|
+ Changed date for release 10.7-beta.
|
|
|
|
o Graphics Representations:
|
|
------------------------
|
|
+ HepPolyhedron, G4Polyhedron: added HepPolyhedronTet.
|
|
+ G4VisAttributes: clarify that if number of cloud points (for cloud style
|
|
drawing) is <= 0, this is to be interpreted as under control of the
|
|
viewer, i.e., to be decided by the viewer. Otherwise this number is to be
|
|
drawn. Zero is the default value, which may be changed by invoking the
|
|
method SetForceNumberOfCloudPoints(); also possible to force cloud
|
|
drawing with SetForceCloud().
|
|
+ Improved deprecation message for G4AttDefs::operator<<().
|
|
+ Cleanup CMake build, removing obsolete granular library options and
|
|
explicit include_directories.
|
|
|
|
o Intercoms
|
|
---------
|
|
+ Removed unnecessary use of deprecated G4USE_STD11 flag in G4AnyMethod.
|
|
+ Cleanup CMake build, removing obsolete granular library options and
|
|
explicit include_directories.
|
|
|
|
o Interfaces
|
|
----------
|
|
+ G4UIQt: replaced use of setTextColor() with adoption of rich text html
|
|
tags (improving visibility in MacOS Dark Mode).
|
|
+ Fixed deprecation warnings being triggered when using Qt-5.15.
|
|
+ Use CMake AUTOMOC to automatically generate and compile Moc sources
|
|
and fixed CMake script to support new CMake system.
|
|
+ Cleanup CMake build, removing obsolete granular library options and
|
|
explicit include_directories.
|
|
|
|
o Materials
|
|
---------
|
|
+ G4MaterialPropertiesTable: added ConstPropertyExists() method.
|
|
+ G4MaterialPropertiesTable, G4MaterialPropertiesIndex: added new
|
|
properties for scintillation allowing 3 time constants and a second
|
|
wavelength shifter in the same material.
|
|
+ Cleanup CMake build, removing obsolete granular library options and
|
|
explicit include_directories.
|
|
|
|
o Parameterisations:
|
|
-----------------
|
|
+ GFlash:
|
|
o Substituting Gamma calculation with corresponding STL functions, as
|
|
suggested in GitHub PR#3. Makes LnGamma calculation 1.4 times faster,
|
|
and Gamma 1.9 times faster.
|
|
o GFlashSamplingShowerParameterisation: added X0eff calculation.
|
|
o Delete local tuning data in GFlashXXXShowerParameterisation class
|
|
destructors.
|
|
|
|
o Particles:
|
|
---------
|
|
+ G4ParticleTable: create/destruct only one instance of G4IonTable and
|
|
associated messenger; define assignment operator and copy constructor
|
|
as deleted; added cache with pointer to selected particle and get/set
|
|
methods.
|
|
+ G4DynamicParticle: added GetBeta() method.
|
|
+ G4OpticalPhoton: define PDG code as "-22".
|
|
+ G4NuclideTable: added destruction of messenger
|
|
+ Added move operators to G4DynamicParticle.
|
|
Code revision for c++11 and cleanup in 'management' module.
|
|
+ Cleanup CMake build, removing obsolete granular library options and
|
|
explicit include_directories.
|
|
+ Fixed Coverity warning.
|
|
|
|
o Persistency:
|
|
-----------
|
|
+ Cleanup CMake build, removing obsolete granular library options and
|
|
explicit include_directories.
|
|
+ ASCII:
|
|
o Fixed Coverity defects warnings.
|
|
+ GDML:
|
|
o Fixed reading and writing of const properties of materials.
|
|
Matrices of size 1x1 are now used both for writing out and reading in
|
|
of const material. This fixes the inconsistency (using constants by the
|
|
writer) found in the code. Const material properties with the same name
|
|
(in different materials) are now written out with the properties table
|
|
address appended.
|
|
|
|
o Physics Lists:
|
|
-------------
|
|
+ Fixes to CMake scripts to support new CMake system.
|
|
+ Builders:
|
|
o Revised all classes to remove unnecessary members, not destruct models
|
|
and cross-sections and use updated instantiation of string models.
|
|
This should help to achieve full deletion of hadronic physics objects
|
|
at the end of run.
|
|
o G4QGSPAntiBarionBuilder: created new class to handle anti_proton and
|
|
anti_neutron at high energies with QGSP. For the light anti-ions
|
|
(anti_deuteron, anti_triton, anti_He3, and anti_alpha), currently QGSP
|
|
cannot handle them, therefore FTFP is used.
|
|
o G4VHyperonBuilder, G4HyperonBuilder, G4HyperonQGSPBuilder: new classes
|
|
to allow alternative builders for hyperons (and anti-hyperons).
|
|
The class G4HyperonQGSPBuilder uses QGSP model to handle hyperons (and
|
|
anti-hyperons) at high energies.
|
|
o G4HyperonFTFPBuilder: now it derives from G4VHyperonBuilder (physics
|
|
behind remains unchanged, i.e. it is still based on BERT and FTFP
|
|
models).
|
|
o G4HadronicBuilder: new utility class to build kaons, hyperons, and b-,
|
|
c- particles.
|
|
o Added second wavelength shifter optical process to the
|
|
OrderingParameterTable.
|
|
+ Constructors:
|
|
o decay:
|
|
- G4RadioactiveDecayPhysics: enabled flag for isomer production,
|
|
required after fix to problem report #2226.
|
|
Updated initialisation to be coherent with recent updates in
|
|
initialisation of atomic de-excitation.
|
|
- G4DecayPhysics, G4RadioactiveDecayPhysics, G4SpinDecayPhysics,
|
|
G4UnknownDecayPhysics: general cleanup. Removed thread local pointers,
|
|
avoid deleting objects; use C++11 keywords; use standard signatures
|
|
for constructors; define builder type for the main constructor
|
|
G4DecayPhysics (bDecay, for others bUnknown).
|
|
o electromagnetic:
|
|
- G4OpticalPhysics, G4OpticalPhysicsMessenger: added settings for
|
|
G4Scintillation to use 3 time constants. Added second wavelength
|
|
shifter optical process to constructors.
|
|
- G4EmBuilder: new utility class to allow reducing code duplication for
|
|
standard and low-energy EM physics constructors. Includes flag for
|
|
allowing choice of multiple-scattering model.
|
|
- G4EmStandardPhysics_option1: switch to use new G4EmBuilder utility;
|
|
fixed StepFunction definition.
|
|
- G4EmStandardPhysics_option3: switch to use new G4EmBuilder utility;
|
|
use ICRU90 stopping power data for water and air.
|
|
- Removed duplicate code by using G4EmBuilder in several constructors,
|
|
fixed definition of StepFunction, use the same flag as hadronic
|
|
physics to enable EM interaction of b- and c- mesons and baryons.
|
|
- G4EmModelActivator: use same options for physics per region as used
|
|
in EM constructors recently updated.
|
|
- G4LivermorePolarizedPhysics: use inheritance from G4LivermorePhysics.
|
|
- G4EmDNAModelActivator: extended to extra available DNA options
|
|
(DNA_Opt2, DNA_Opt4, DNA_Opt4a, DNA_Opt6, DNA_Opt6a, DNA_Opt7).
|
|
- Optimisation in initialisation of G4EmDNAChemistry_option3.
|
|
- Use C++11 features in several constructors.
|
|
o gamma_lepto_nuclear:
|
|
- G4EmExtraPhysics, G4EmMessenger: added low-energy limit, set method,
|
|
and UI command defining low-energy gamma-nuclear model, which is
|
|
using de-excitation module and providing isomer production and
|
|
gamma transitions.
|
|
- G4EmExtraPhysics: extension to anti_nu_mu, nu_e and anti_nu_e
|
|
processes-models.
|
|
o hadron_inelastic:
|
|
- Use the new builder class G4QGSPAntiBarionBuilder to handle
|
|
anti_proton and anti_neutron at high energies with QGSP.
|
|
For the light anti-ions - anti_deuteron, anti_triton, anti_He3 and
|
|
anti_alpha - currently QGSP cannot handle them, therefore FTFP is used.
|
|
- In all the inelastic physics constructors which are using the builder
|
|
G4HyperonFTFPBuilder, introduced the new builder G4HyperonBuilder;
|
|
moreover, the new builder G4HyperonQGSPBuilder is used now in all
|
|
QGS-based inelastic physics constructor for hyperons (and
|
|
anti-hyperons) at high energies, while keeping using
|
|
G4HyperonFTFPBuilder at lower energies.
|
|
- G4HadronPhysicsFTFP_BERT, G4HadronPhysicsQGSP_BERT,
|
|
G4HadronInelasticQBBC: added b- and c- particles.
|
|
- G4HadronPhysicsQGSP_BIC_HP, G4HadronPhysicsQGSP_BIC_AllHP: refactoring
|
|
consistently with all others. For G4HadronPhysicsQGSP_BIC_HP, the
|
|
physics remains unchanged; for G4HadronPhysicsQGSP_BIC_AllHP, the
|
|
physics remains unchanged except for the transition region between
|
|
Binary and ProtonHP which is now 190-200 MeV (instead than 199-200),
|
|
as for light ions.
|
|
o ions:
|
|
- Cleanup of constructors: fixed names; made all constructor signatures
|
|
universal, removed thread local members, added c++11 keywords.
|
|
o stopping:
|
|
- Cleanup of constructors: fixed names; made all constructor signatures
|
|
universal, removed thread local members, added c++11 keywords.
|
|
+ utils:
|
|
o G4HadParticles: new utility providing several lists of PDG codes for
|
|
kaons, hyperons, b- and c- particles in order to be used for
|
|
construction of hadronic physics. Updated list of heavy EM particles.
|
|
|
|
o Electromagnetic Processes:
|
|
-------------------------
|
|
+ DNA:
|
|
o Added classes for IRT; added features in management classes for IRT
|
|
(G4ITReaction, G4ITModelProcessor ...).
|
|
o Added features in G4DNAMolecularReactionTable for GFDE.
|
|
o Added molecules (Oxygen, O2, O3, HO2) from: Plante et al.(2017).
|
|
o G4MoleculeDefinition: copy constructor and assignment operator are not
|
|
allowed (as for G4ParticleDefinition). Now deleted.
|
|
o Revised displacement of OH radicals of B1A1 dissociation based on
|
|
momentum conservation in G4DNAWaterDissociationDisplacer.
|
|
o Fix to CMake script to support new CMake system.
|
|
+ Low Energy:
|
|
o Added new model for polarized gamma elastic scattering, provided by
|
|
the JAEA group. Updated existing process (G4JAEAElasticScattering) and
|
|
model (G4JAEAElasticScatteringModel) in order to comply with the new
|
|
data format. Changed initialisation of JAEA models.
|
|
o G4LivermorePhotoElectricModel: allow "Water" as a name of water
|
|
material for low-energy photo-effect.
|
|
o Added G4LivermoreGammaConversion5DModel class. Reading EPICS2017 data.
|
|
o Change in G4LivermoreGammaConversion to now derive from
|
|
G4PairProductionRelModel. Added missing method InitialiseForElement().
|
|
o Fixed compilation warnings on clang-10.
|
|
+ Standard:
|
|
o G4eplusAnnihilation: fixed problem seen in the rare case, when initial
|
|
energy is null; introducing thermal model of positronium decay to two gammas.
|
|
In this model, the positronium acquires a mean kinetic energy on
|
|
formation, which contributes to a small non-collinearity of the
|
|
gammas, detectable and significant in PET. To activate this model:
|
|
material->GetIonisation()->SetMeanEnergyPerIonPair(meanKE).
|
|
A mean kinetic energy of 5 eV produces a projected acollinearity
|
|
of about 0.5 degrees FWHM, as reported in:
|
|
K.Shibuya et al., IFMBE Proceedings Vol. 14/3 1667 (2007).
|
|
o G4UniversalFluctuation: changed 'nmaxCont' from 16 to 8 for speedup.
|
|
Set value for 'a0' to 42 after optimisations. Minor C++ improvements.
|
|
o G4UrbanMscModel: tuned 'tlimitmin' computation for e- (for e+ kept
|
|
unchanged) and changed parameterisation of 'stepmin'; added two private
|
|
inline methods to reduce code duplication.
|
|
Removed cache and introduced data struct precomputed at initialisation,
|
|
added e- range cut to the data structure.
|
|
o G4BetheHeitler5DModel: change "final" keyword by "override" for virtual
|
|
methods.
|
|
o G4LindhardSorensenData: fixed few numbers in the data table.
|
|
o G4eeToTwoGammaModel: code cleanup; added static flag, which identifies
|
|
if electron motion is taken into account for sampling of acollinearity,
|
|
when annihilation happens at rest; ensuring that by default no extra
|
|
computation is performed; also removed extra printout at initialisation
|
|
and extra data structure.
|
|
o Fixed compilation warnings on clang-10.
|
|
+ Utils:
|
|
o G4EmParameters, G4EmLowEParameters, G4EmLowEParametersMessenger: added
|
|
a new parameter - name of the sub-directory with data for Livermore
|
|
models with variants: "livermore" (default), "epics_2017".
|
|
Comes with G4EMLOW-7.10 data set and higher.
|
|
o G4EmParameters, G4EmParametersMessenger, G4VMultipleScattering:
|
|
removed displacement-beyond-safety option, as may lead to crashes in
|
|
some circomstances, and wrong results in others.
|
|
o G4EmParameters, G4EmParametersMessenger, G4EmExtraParametersMessenger,
|
|
G4VEnergyLossProcess: added two extra sets of StepFunction parameters
|
|
for light ions and generic ions. Added extra UI commands. Modified
|
|
interfaces accordingly. Removed old comments.
|
|
o G4EmLowEParametersMessenger: extended number of DNA PhysicsList options.
|
|
o G4VEmProcess: removed old unused methods; DefinedMaterial() method is
|
|
now protected (needed for AtRest processes).
|
|
o G4LossTableManager: made ResetParameters() method public.
|
|
o G4VAtomicDeexcitation: optimized arrays initialisation.
|
|
o G4EmCalculator: fixed printout.
|
|
+ Xrays:
|
|
o Implemented three time constants for G4Scintillation, and allow
|
|
multiple time constants to work with scintillation by particle type.
|
|
The existing material property names have FAST and SLOW in them, like
|
|
FASTTIMECONSTANT. This doesn't generalize well. Also YIELDRATIO as a
|
|
single value doesn't generalize to three time constants. Proposal is
|
|
to create new names SCINTILLATIONTIMECONSTANT1/2/3 and the same for
|
|
other parameters. The existing names are kept for backwards
|
|
compatibility, with the idea to remove them in the next major release.
|
|
There is a flag in G4Scintillation, with messenger command in the
|
|
OpticalPhysics list, to use the new method:
|
|
/process/optical/scintillation/setEnhancedTimeConstants true.
|
|
Results are unchanged if using same values.
|
|
Set verbosity levels correctly.
|
|
o G4VXTRenergyLoss: fixed destructor.
|
|
o Code formatting.
|
|
|
|
o Generic Processes:
|
|
-----------------
|
|
+ Biasing:
|
|
o G4ImportanceProcess: added process type as fParallel.
|
|
+ Cuts:
|
|
o Revision for use of c++11 constructs. Code cleanup and formatting.
|
|
+ Management:
|
|
o G4ProcessManagerMessenger: use cache pointer of selected particle
|
|
in the G4ParticleTable class.
|
|
o G4ProcessTable: enabled deletion of all processes except
|
|
G4Transportation at the end of run.
|
|
o Fixed Coverity warning for uninitialised data in G4VProcess.
|
|
o C++11 revision and code cleanup/formatting.
|
|
+ Optical:
|
|
o Added second wavelength shifting process, G4OpWLS2, within the same
|
|
material.
|
|
o Use new ConstPropertyExists(int) method rather than passing strings.
|
|
o G4OpRayleigh: avoid double deletion of property vectors.
|
|
o Code cleanup and improved readability.
|
|
+ Parameterisation:
|
|
o G4FastSimulationHelper: merged ActivateFastSimulation() calls for mass
|
|
and parallel geometry cases.
|
|
o G4FastSimulationManager, G4VFastSimulationModel: removed redefinition
|
|
of G4Envelope type.
|
|
o Added sanity check for root logical volumes in regions for
|
|
G4GlobalFastSimulationManager. UI command /param/showSetup works also
|
|
if no parallel world is present.
|
|
+ Scoring:
|
|
o G4ParallelWorldProcess, G4ParallelWorldScoringProcess: use new PDG
|
|
code for optical photon, "-22".
|
|
o G4ParallelWorldProcess: make some private methods and data members
|
|
protected so that this class can be extendable.
|
|
|
|
o Hadronic Processes:
|
|
------------------
|
|
+ Fixes to CMake scripts to support new CMake system.
|
|
+ cross_sections
|
|
o G4ElNeutrinoNucleusTotXsc: new class for (nu_e,anti_nu_e)-nucleus
|
|
cross-sections.
|
|
o G4PhotoNuclearCrossSection: corrected threshold for
|
|
gamma + p -> pi0 + p, extended for use on 3H and 3He targets.
|
|
o G4HadronNucleonXsc: general clean-up of the code; use PDG number
|
|
instead of particle pointer; removed instantiation of most of hadrons,
|
|
optimisation in selection of parameterisation parameters.
|
|
o G4CrossSectionElastic, G4CrossSectionInelastic: fix for ions and
|
|
anti-ions, where the max energy of applicability of the (elastic and
|
|
inelastic) cross-sections must scale with the absolute baryonic number;
|
|
however, the cross-sections objects are often shared between the
|
|
different types of ions (d, t, He3, alpha, and genericIon), therefore
|
|
we scale by a large value (256, safely larger than the number of
|
|
nucleons of the heaviest nuclides).
|
|
o Fixed compilation warnings on clang-10.
|
|
+ management
|
|
o G4HadronicProcess: fixed Coverity defect warning to EP check method for
|
|
the case when primary particle remains in the interaction.
|
|
o G4HadronicProcessStore: in the method Dump(), check the internal
|
|
verbosity level as well as the newly introduced global hadronic
|
|
verbosity level, returning immediately (without printing anything) if
|
|
one of these is 0. Extended default initialisation printout to sigma-,
|
|
D-, B-. Removed check for G4HadronicException, where it cannot be;
|
|
limit printout on kaon0 in final state.
|
|
o Removed use of deprecated G4USE_STD11 flag.
|
|
o G4HadLeadBias: replaced 'G4int' with 'size_t' to fix warnings
|
|
on Windows.
|
|
+ models/binary_cascade
|
|
o G4BinaryCascade: fixed memory leak at exit.
|
|
+ models/cascade
|
|
o Fixed non-conservation warnings coming from G4HadronicProcess due to
|
|
sub-threshold reactions in Bertini. Sub-threshold reactions are now
|
|
treated as having a "non-interaction" final state, that is, the initial
|
|
particles are simply copied to the final state.
|
|
o Fixed compilation warnings on clang-10.
|
|
+ models/de_excitation
|
|
o G4PhotonEvaporation, G4DeexPrecoParameters, G4DeexParametersMessenger:
|
|
added extra flag 'IsomerProduction'; if enabled. photon evaporation
|
|
samples the time of gamma transition; added C++ interface and UI command
|
|
allowing to set this flag; radioactive decay constructor should enable
|
|
this parameter. Addressing problem report #2226.
|
|
o G4DeexPrecoParameters: in method Dump(), check the global verbosity
|
|
level of hadronics (if zero, do not print anything).
|
|
o Fixed compilation warnings on clang-10.
|
|
+ models/inclxx
|
|
o G4INCLXXInterfaceStore: in method EmitBigWarning(), check the global
|
|
verbosity level of hadronics (if zero, do not print anything).
|
|
o Fixed compilation warnings on clang-10.
|
|
+ models/lepto_nuclear
|
|
o G4NuMuNucleusCcModel, G4NeutrinoNucleusModel, new access methods
|
|
and minor fixes in in nu-mu nucleus model.
|
|
o Added classes G4ANuElNucleusCcModel and G4ANuElNucleusNcModel,
|
|
for anti_nu_e. Initialization from G4PARTICLEXS (neutrino/anti_nu_e).
|
|
o Added classes G4NuElNucleusCcModel and G4NuElNucleusNcModel,
|
|
for nu_e. Initialization from G4PARTICLEXS (neutrino/nu_e).
|
|
o Added classes G4ANuMuNucleusCcModel and G4ANuMuNucleusNcModel,
|
|
for anti_mu_nu. Initialization from G4PARTICLEXS (neutrino/anti_nu_mu).
|
|
o G4NuMuNucleusCcModel, G4NuMuNucleusNcModel, G4NeutrinoNucleusModel:
|
|
rearrangement of initialisation methods and arrays.
|
|
Fixes in CoherentPion() method, cleanup of Cc and Nc.
|
|
o G4NeutrinoNucleusModel: added K+, K- in final state.
|
|
o Fixed Coverity warnings for defects.
|
|
+ models/management
|
|
o G4HadronicInteractionRegistry: delete HP and PHP at the end of run.
|
|
o G4HadronicInteraction: provide default implementation for all virtual
|
|
methods.
|
|
o G4VHighEnergyGenerator, G4VIntraNuclearTransportModel,
|
|
G4VPreCompoundModel: cleaned up: removed old commented lines,
|
|
code format, C++11 keywords.
|
|
+ models/particle_hp
|
|
o Allow printout only if the global hadronic verbosity level is not zero.
|
|
o G4ParticleHPHash, G4ParticleHPCaptureFS: fixes for implicit conversion
|
|
between 'size_t' and 'G4int', to avoid warnings on Windows.
|
|
+ models/parton_string
|
|
o Improved treatment of antibaryon interactions in QGS.
|
|
In G4QGSMFragmentation, corrected the treatment of low-mass diquark-
|
|
antidiquark strings. In addition to this, introduced the Mt
|
|
distribution of produced hadrons.
|
|
In G4VLongitudinalStringDecay, introduced in SetMinimalStringMass()
|
|
a check that the strings are of allowed type: quark-antiquark, diquark-
|
|
antidiquark, quark-diquark and antiquark-antidiquark. Introduced also
|
|
for diquark-antidiquark strings a special algorithm (already present
|
|
for the other types of allowed strings) for treating low-mass strings
|
|
with masses below known hadrons.
|
|
o In G4QGSParticipants, the average transverse momentum of partons in a
|
|
hadron is set to zero (according to the study of transverse momentum
|
|
distributions of hadrons produced in hadronic interactions, in
|
|
particular the study of Xf - Pt correlations presented by the NA49
|
|
Collaboration). In G4QuarkExchange, the reggeon exchanges are now
|
|
treated as annihilation and creation of quark-antiquark pairs (to
|
|
reflect in inelastic processes the non-vacuum reggeon exchanges present
|
|
in antiparticle-particle elastic scattering amplitudes).
|
|
o G4VLongitudinalStringDecay, G4LundStringFragmentation,
|
|
G4ExcitedStringDecay: inherit from G4HadronicInteraction; destruction
|
|
of these models at the end of run is now done by the hadron model
|
|
store; removed implementations of private operators.
|
|
o G4VStringFragmentation: use inheritance from G4HadronicInteraction;
|
|
removed implementations of private operators.
|
|
o G4SPBaryonTable: changed return type of the method 'length()' from
|
|
'double' to 'size_t', to fix warnings on Windows.
|
|
o G4FTFModel, G4FTFParticipants: clean-up: removed unused methods,
|
|
delete operators, use of C++11 keywords.
|
|
o G4VParticipants, G4VPartonStringModel, G4VStringFragmentation,
|
|
G4StringModel: clean-up; removed unused methods, delete operators,
|
|
use of C++11 keywords.
|
|
o G4QGSModel: clean-up; removed unused methods, delete operators, use of
|
|
C++11 keywords, moved inline implementation to source.
|
|
+ models/qmd
|
|
o G4QMDReaction: added code in ApplyYourself() to get cross-section when
|
|
projectile is pion. Replaced data member G4PiNuclearCrossSection with
|
|
G4BGGPionElasticXS and G4BGGPionInelasticXS.
|
|
In G4QMDGroundStateNucleus constructor, move check for p or n
|
|
projectile earlier in code so baryon number can be conserved.
|
|
Addressing problem report #2236.
|
|
+ models/quasi_elastic
|
|
o G4QuasiElRatios: fixed memory leak at exit.
|
|
+ models/radioactive_decay
|
|
o G4RadioactiveDecayBase, G4RadioactiveDecay: in BuildPhysicsTable(),
|
|
check the global hadronic verbosity level before printing out
|
|
information.
|
|
+ models/rpg
|
|
o Fixed Coverity warnings for unused variables.
|
|
+ models/theo_high_energy
|
|
o G4QuasiElasticChannel: use inheritance from G4HadronicInteraction.
|
|
In G4TheoFSGenerator do not destruct G4QuasiElasticChannel.
|
|
o G4QuasiElasticChannel, G4TheoFSGenerator: clean-up; use of C++11
|
|
keywords and loops, removed unused methods, formatting.
|
|
+ models/util
|
|
o Fixed compilation warnings on clang-10.
|
|
+ processes
|
|
o G4MuNeutrinoNucleusProcess, G4ElNeutrinoNucleusProcess: extended to
|
|
anti_nu_mu, nu_e and anti_nu_e.
|
|
+ stopping
|
|
o G4HadronicAbsorptionFritiof,
|
|
G4HadronicAbsorptionFritiofWithWithBinaryCascade: simplified
|
|
instantiation of the FTF model, do not destruct its components.
|
|
o G4MuonicAtomDecay: fixed Coverity defect warning.
|
|
+ util
|
|
o G4HadronicParameters: added modifiers for Cascade-FTF transition.
|
|
Creates the new messenger.
|
|
o G4HadronicParametersMessenger: created new messenger class for
|
|
G4HadronicParameters. For the time being it has only the global
|
|
verbosity level for hadronics.
|
|
o G4HadFinalState: fixed warning on Windows for implicit conversions
|
|
from 'size_t' to 'G4int'.
|
|
|
|
o Readout
|
|
-------
|
|
+ Cleanup CMake build, removing obsolete granular library options and
|
|
explicit include_directories.
|
|
|
|
o Run
|
|
---
|
|
+ G4RunManager, G4WorkerRunManager: added layered mass geometry option
|
|
for the new "probe" scoring mesh.
|
|
+ G4RunManager: do not call G4ParticleTable for Messenger deletion.
|
|
+ Modified G4MTRunManager to enable inheritance for new G4TaskRunManager.
|
|
+ G4MTRunManager, G4RunManager: fixes for windows, to avoid inline static
|
|
methods and use export flag G4RUN_DLL for static data.
|
|
+ Added second wavelength shifter process to G4PhysicsListHelper.
|
|
+ G4VPhysicsConstructor: added harmless call to G4HadronicParameters in
|
|
constructors, setting a default parameter; needed to create the instance
|
|
of the G4HadronicParameters singleton before run initialization.
|
|
+ General code formatting.
|
|
+ Cleanup CMake build, removing obsolete granular library options and
|
|
explicit include_directories.
|
|
|
|
o Tasking
|
|
-------
|
|
+ New module implementing a new Geant4 run manager, G4TaskRunManager,
|
|
enabling use of the PTL tasking system for the event loop. The tasking
|
|
system is fully compatible with Intel TBB, which can be selected if
|
|
GEANT4_USE_TBB=ON is specified when configuring CMake. The default
|
|
behavior, however, is to submit the tasks to an internal thread-pool
|
|
and task-queue.
|
|
A comprehensive description of the system and options provided can be
|
|
found in the README document located within this module.
|
|
|
|
o Track & Tracking
|
|
----------------
|
|
+ G4Track: use new G4OpticalPhoton PDG code; removed static thread local
|
|
variables; slightly simplified velocity computation; fixed Coverity
|
|
warnings connected with unnecessary checks for valid pointers to G4Step
|
|
and G4DynamicParticle; removed commented code.
|
|
Avoid using velocity table, use GetBeta() method from G4DynamicParticle
|
|
instead; expected minor speedup.
|
|
+ Minor c++11 revision; code cleanup and formatting in tracking module.
|
|
+ Fixed minor Coverity defect for uninitialised data in G4SteppingManager.
|
|
+ Cleanup CMake build, removing obsolete granular library options and
|
|

o Fixed case where models with no extent do not contribute to scene's
|
|
extent.
|
|
o Trap infinite loop when looking for a fallback graphics system when
|
|
issuing "/vis/sceneHandler/create".
|
|
o G4VisExecutive: added support for OIQT driver, via "OIQT" or "OI"
|

|
|
+ OpenInventor:
|
|
o Enable configuration for OIQT driver, as orthogonal to OIX and OIXE.
|
|
o Corrections to OIQT viewer and changes for use with Qt UI.
|
|
|
|
o Data Sets:
|
|
---------
|
|
+ G4EMLOW-7.12:
|
|
o Added new cross-section files for protons (HT).
|
|
o Added EPICS2017 data for gamma conversion (ZL).
|
|
o Added new JAEA elastic polarized gamma scattering data files
|
|
in compressed format.
|
|
o Added a new numerical DCS set for e-/e+ elastic scattering
|
|
obtained by numerical Dirac Partial Wave Analysis (DPWA).
|
|
More information can be found in the 'dpwa/Readme.txt' file.
|
|
|
|
o Examples:

+ Updated reference outputs, macros, READMEs and scripts.
|
|
+ advanced/air_shower
|
|
o Added missing include statement in UltraDetectorConstruction.
|
|
+ advanced/fastAerosol
|
|
o New example showing use of FastAerosol geometry classes, allowing to
|
|
efficiently and accurately simulate particle transport through aerosols
|
|
containing billions of randomly-positioned droplets, using an ordinary
|
|
workstation. See: MacFadden, N., Knaian, A., "Efficient Modeling of
|
|
Particle Transport through Aerosols in Geant4", manuscript in
|
|
preparation, 2020.

(Number of species X) / (100 eV of deposited energy), as a function of
|
|
time and LET. The details are described in the following paper:
|
|
J. Appl. Phys. 125 (2019) 104301.
|
|
+ extended/optical/OpNovice2
|
|
o Use new scintillation time constant parameter.
|
|
o Added code to generate statistics for wavelength shifting.
|
|
o Added wls.mac to test WLS and new process WLS2.
|
|
o Removed string comparisons and redundant calls in SteppingAction.
|
|
o Removed redundant G4AnalysisManager::Instance() calls.
|
|
+ extended/parallel/TBB
|
|
o Updated to use new tasking system which is fully compatible with TBB.
|
|
+ extended/parallel/ThreadsafeScorers
|
|
o Updated to use new tasking system; forcing use of G4TaskRunManager.
|
|
o Added example of user code leveraging tasking in TSRunAction; it
|
|
leverages tasks on the master thread at the end of the run to generate
|
|
some strings of output via a nested hierarchy of tasks and uses the
|
|
features of the G4TaskGroup to combine the strings in the order that
|
|
they were submitted to the task-group (thus producing the same output
|
|
result as the serial version).
|
|
+ extended/persistency/gdml/G01
|
|
o Use [] brackets in loop.gdml sample to show how to index names
|
|
and dimensions in loops.
|
|
+ extended/persistency/P01
|
|
o Fixed CMake script for search or Root macros.
|
|
+ extended/radioactivedecay/Activation
|
|
o GammaNuclearPhysics: added G4LowEGammaNuclearModel.
|
|
o In Run, corrected a protection on maximum number of histograms.
