|
|
--------------------------------
|
|
|
|
25 June 2010
|
|
|
|
List of main features and fixes included in this Beta release since 9.3.p01:
|
|
|
|
o Configuration:
|
|
-------------
|
|
+ Configure script:
|
|
o Protected echos on LD_LIBRARY_PATH so that output from use of
|
|
Configure post-install is clean.
|
|
o Added removal of quotes from make version string to handle non-English
|
|
language systems.
|
|
o Fixed selection of XERCESCROOT path for Windows.
|
|
o Added new data set G4NEUTRONXS (Evaluated neutron cross section
|
|
data, version 1.0), controlled by variable G4NEUTRONXSDATA.
|
|
o Updated data set G4EMLOW to version 6.13.
|
|
+ Removed 'leading_particle' hadronic module from include paths list.
|
|
+ Increased stack size on WIN32-VC setup (i.e. 8MB as on Linux), adding
|
|
the option to LDFLAGS.
|
|
|
|
o Digits+Hits:
|
|
-----------
|
|
+ Added missing virtual destructor to G4VScoringMesh and removed
|
|
unnecessary virtual qualifiers to G4ScoringBox.
|
|
|
|
o Environments:
|
|
------------
|
|
+ G4Py:
|
|
o Revised usage of MultipleScattering classes to make use of new particle
|
|
based processes.
|
|
o Fixed bug in wrapping of G4GDMLParser.
|
|

|
|
+ Added few accessors methods to G4SPSEneDistribution class.
|
|
+ Removed obsolete CLHEP_HepMC option from G4EventManager class.
|
|
|
|
o Geometry:
|
|
--------
|
|
+ solids/Boolean:
|
|
o Introduced recursive algorithm in CreatePolyhedron() for Boolean
|
|
operations: it uses HepPolyhedronProcessor from 'graphics_reps' module,
|
|
using new technique in attempt to avoid numerical problems for the
|
|
calculation of the polyhedron in BooleanProcessor. It allows to try
|
|
all permutations, also for Booleans of Booleans.
|
|
Helps in reducing the number of cases of "Error in Boolean processor"
|
|
for visualization; still some stubborn cases are left.
|
|

|
|
o G4Box: first implementation of speed improvements and corrections from
|
|
joint code review of G4Box class: introduced half-tolerance constants
|
|
and better logic in some conditional statements. Some code cleanup.
|
|
o G4Orb: modified DistanceToIn(p,v) to be more consistent with Inside(p).
|
|
+ solids/specific:
|
|
o Introducing new G4GenericTrap shape, a new solid representing an
|
|
arbitrary trapezoid with up to 8 vertices standing on two parallel
|
|
planes perpendicular to the Z axis.
|
|
o Fix in G4TriangularFacet and G4TessellatedSolid to correct treatment of
|
|
optical photon transport related to internal reflection at surface.
|
|
Addresses problem report #1103.
|
|
o G4ExtrudedSolid: eliminated requirement for clockwise ordering of
|
|

|
|
are defined anti-clockwise their ordering is reverted.
|
|
Fix in polygon facet triangularization for consequent concave vertices.
|
|
o Fixed deletion of internal arrays in CreatePolyhedron() for G4Polycone
|
|
and G4Polyhedra.
|
|

|
|
in G4VGraphicsScene.
|
|

|
|
to G4VVisManager in order to distinguish usage and in preparation for
|
|
'i_mode' migration.
|
|
|
|
o Intercoms:
|
|
---------

|
|
Removed possibility to use custom cuts for fluorescence/Auger.
|
|
Main cuts from G4ProductionCutsTable are always used, for consistency.

|
multi-element atomic oscillators used in Penelope Compton and
|
|
Ionisation models. Compliant with Penelope-2008.
|

|
classes substitute the G4ecpssrCrossSection class, fixing existing
|
|
bugs and improving the goodness of the results especially at higher
|
|
energies.
|
|
The Geant4 PIXE developers are really thankful to Maria Grazia Pia
|
|
for searching for bugs in the previous Geant4 release, pointing
|
|
existing problems and propose solution in a very collaborative way
|
|
in: M.G.Pia et al., CHEP-2009 conference, March 2009, Prague (Czech
|
|
Republic).
|
|
- G4empCrossSection and G4teoCrossSection classes: these two classes,
|
|
deriving from G4VhShellCrossSection, provide the interface to
|
|
empirical ionization cross sections (Orlic for L shells and Paul
|
|
for K).
|
|
- G4hShellCrossSection, G4hShellCrossSectionDoubleExp,
|
|
G4hShellCrossSectionDoubleExpData, G4hShellCrossSectionExp,
|
|
G4hShellCrossSectionExpData classes are now discontinued.
|
|
- G4hLowEnergyIonisation has been updated to follow the new design
|
|
and let the user chose which model to use for the calculation of shell
|
|
ionization cross section through the method SelectShellIonisationCS().
|
|
Dependencies on old methods for cross sectiuon calculation have been
|
|
removed.

|
|
G4VEnergyLossProcess and avoid size mismatch in G4LossTableBuilder.
|
|
+ Standard:
|
|
o G4GoudsmitSaundersonMscModel: fixed problems of small angle theta
|
|
distributions. Improved numerical stability of computations for small
|
|
angles by direct cross-section calculation, now inverse of the inverse
|
|
angular sampling without large angle rejection method longitudinal
|
|
displacement is computed exactly from <z>.
|
|

|
|
potential.

|
|
o Fixed G4_O data in G4ASTARStopping. Fixed G4_Pt and G4_PROPANE data in
|

o G4BraggModel: above 2 MeV use ICRU'49 parameterisation for all atoms.
|
|
o New model G4ICRU73QOModel for anti-particles
|
|
o G4hIonisation: use new G4ICRU73QOModel for negatively charged particles
|
|
instead of G4BraggModel, which used to be applied for positevely
|
|
charged particles only. This modification provides simulation of
|
|
Barkas effect at low energies (before the effect was simulated at
|
|
higher energies in G4BetheBlochModel).
|
|
The high energy limit for the new model is the same as for G4BraggModel
|
|
(2 MeV for protons/anti-protons).
|
|
o G4WentzelOKandVIxSection: new class to compute cross sections and
|
|
sample scattering angle.
|
|
o G4WentzelVIModel, G4eCoulombScatteringModel, G4CoulombScatteringModel:
|
|
use new class G4WentzelOKandVIxSection.
|
|
o G4WentzelVIModel: optimized method of step limitation.
|
|
o G4WentzelVIModel, G4eCoulombScatteringModel: added momentum dependent
|
|
limit of scattering angle between single and multiple scattering which

|
|
initialisation.
|
|
o Removed obsolete models: G4UrbanMscModel, G4UrbanMscModel2,

G4UrbanMscModel71, G4MultipleScattering, G4ComptonScattering52,
|
|

|
+ Utils:
|
|
o G4VMscModel, G4VMultipleScattering: set skin=1.0 as default.
|
|

|
|
is used in G4VEmModel for initialisation of G4EmElementSelector.
|
|
Addressing problem report #1115.
|
|
Added methods PreparePhsyicsTables(), BuildPhysicsTables(), fixing
|
|
initialisation of models via G4EmConfigurator.
|
|
o G4EmProcessOptions: removed extra initialisation code, already existing
|
|
in G4LossTableManager.
|
|
o G4VEnergyLossProcess, G4VEmProcess, G4VMultipleScattering: added
|
|
calls to new G4LossTableManager methods PreparePhsyicsTables() and

|
|
and G4VEmModel classes.
|
|
o G4VEmProcess: cleanup printout at initialisation for scattering process.
|
|
o G4VEmModel: added method ChargeSquareRatio() to access current charge
|
|
of an ion; use this method in G4VEnergyLossProcess.
|
|
o G4VEnergyLossProcess: call CorrectionsAlongStep() only for ions (minor
|
|
CPU saving). Use the same method to build cross section table
|
|
as DEDX table (use copy constructors to reduce number of calls to exp()).
|
|
o G4EmCalculator: fix in GetCrossSection() method.
|
|
o G4EmElementSelector: use Spline flag to construct vectors probabilities.
|
|
o G4EmModelManager: do not use min energy cut defined by models, so
|
|
production threshold is defined only by range to energy conversion and
|
|
is limited only by low limit of energy threshold defined in 'cut'
|
|
category.
|
|
o G4EmConfigurator: fix for case of more than one model added per a
|
|
process.
|
|

|
|
GetEnergyMomentumCheckLevels(), which implement energy/momentum
|
|
checking. Some code cleanup.
|
|
o New G4HadronicEPTestMessenger class to provide energy/momentum test
|
|
commands available in UI.
|
|
+ models/cascade
|
|
o Replaced all uses of bindingEnergy() (local Bertini method) with the
|
|
Geant4 standard G4NucleiProperties::GetBindingEnergy(A,Z) in classes
|
|
G4IntraNuclearCascader, G4InuclCollider, G4NucleiModel, G4Fissioner,
|
|
G4EquilibriumModel and G4NonEquilibriumModel.
|
|
G4Fissioner still uses Bertini method bindingEnergyAsymptotic().

|
|
subclasses, which implement the Bertini-specific dibaryon states.

|
|
nucleon-nucleon, kaon-nucleon anf hyperon-nucleon scattering.
|

|
|
types to Geant4 standard particle types.
|
|
o Energy/momentum checks added which remove large energy non-conservation
|
|
events.
|
|
o Improved memory management: removed allocation of strings in various
|
|
constuctors; replaced several cases of return-by-value with const or
|
|
non-const reference, or by use of buffers.
|
|
o CPU speed improvements from the removal of unnecessary class
|
|
instantiations.. Code re-organization to permit more speed improvements

o G4DiscreteGammaTransition: removed unphysical corrections of gamma
|
|

|
|
energy in case of electron emission.
|
|
o G4ExcitationHandler: apply FermiBreakUp to fragments with A>1 (before
|
|
was A>4) in order to reduce number of fake gamma produced in
|
|
deexcitation of light fragments; added parameter 'minExcitation' equal
|
|

|
|
FermiBreakUp cannot deexcite a fragment. Added SetParameters() method.
|
|
o G4Evaporation: rewritten BreakUp() method; added Initialise() method at
|
|
construction, to setup all options and not at run time.

|
|
+ models/radioactive_decay
|
|
o G4RadioactiveDecay:
|
|
- In LoadDecayTable() create a decay table for isomers not included
|
|
in RDM database and assume they all under go IT decay.
|
|
- After DoDecay() check if there is any secondary produced.
|
|
Kill the track if not to prevent infinite loop.
|
|
- Insert a special treatment for K-40 beta decay; applied SetICM(),
|
|
SetARM() and SetHLThreshold() to a decay channel.
|
|
Addresses problem report #1068.
|
|
- Make sure the propertime is positive; negative case occures when the
|
|
isomer is not in RDM database and its f-l is set to -1 by default.
|
|
- Corrected typo in declaration.
|
|
o G4NuclearDecayChannel: added initialisation to all three constructors.
|
|
o G4RadioactiveDecay, G4NuclearDecayChannel:
|
|
- Limit the shell index to < 7, as required by the ARM. Changed to use
|
|
BreakUp() rather than BreakItUp() so to limit to one transition per
|
|
step when ICM is applied. Addresses problem report #1001.
|
|
- Added private member data 'applyICM', 'applyARM' and
|
|
'halflifethresold' with their modifiers.
|
|
o G4RadioactiveDecayMessenger: added the UI commands for SetICM, SETARM
|
|
and SetHLThreshold.
|
|
+ models/util
|
|
o G4Fragment: do not add any shift to excitation energy but use direct
|
|
computation (this is needed to avoid infinite loop in gamma
|
|
deexcitation); use G4NucleiProperties to access or compute ground
|
|
state mass. Allow e- as a fragment.
|
|
Added inline method ComputeGroundStateMass(); added accessors for
|
|
integer Z and A; added ExcitationEnergyWarning() method.
|
|
Minor speedup by adding member and access method to GroundStateMass.
|
|
Some code cleanup: single return in inline methods.
|
|
+ util
|
|
o Added interface for integer A&Z to G4Nucleus, and modified G4LightMedia,
|
|
G4HadronicWhiteBoard and G4ReactionDynamics to use the new interface.
|
|
|
|
o Optical Processes:
|
|
-----------------
|
|
+ Fix for backpainted surfaces to avoid applying twice reflectivity.
|
|
Addressing problem report #1114.
|
|
+ Refashioned code in the case of type 'dielectric_dielect'.
|
|
+ Fixed sampling of 'theFacetNormal' for 'polishedbackpainted' material
|
|
in G4OpBoundaryProcess::DielectricDielectric() method. Address problem
|
|
reported on Hypernews Optical Processes Forum, thread #334.
|
|
+ Modified G4OpBoundaryProcess to call ProposeLocalEnergyDeposit() every
|
|
time a photon is in 'fStopAndKill' state because of NoRINDEX. This will
|
|
trigger scoring when a photon encounters a volume not defined as an
|
|
optical medium.
|
|
|
|
o Run
|
|
---
|
|
+ Corrected printing of number of events processed on run abortion.
|
|
+ Fixed definition of path for Windows in G4RunManager for random seeds
|
|
directory: use '\' instead of '/' and suitable system command.
|
|
+ Use "const G4String&" as arguments and return value wherever applicable
|
|
in G4RunManager and G4RunManagerKernel.
|
|
|
|
o Tracking
|
|
--------
|
|
+ G4VTrajectory, G4Trajectory, G4SmoothTrajectory: added deprecation
|
|
message, being printed via G4Exception only once, and only if a user
|
|
invokes with a non-zero value of 'i_mode' in DrawTrajectory().
|
|
|
|
o Visualization:
|
|
-------------
|
|
+ management:
|
|
o Added new "/vis/open" command for OpenGL viewers, "/vis/open OGL".
|
|
This new form allows the same macro to be used whether one is on
|
|
Linux or Windows (calling OGLSX on Linux and OGLSWin32 on Windows).
|
|
When the application has been built with Qt, it will use the Qt form
|
|
of OpenGL; when built with Motif, it will use the Motif form of OpenGL.
|
|
Also added options OGLI and OGLS to force Immediate or Stored modes.
|
|
The user is still free to use the older, specific viewer names, such
|
|
as OGLIX, but the simple form, OGL, will give the most portable macros.
|
|
o Added new "/vis/open" command for OpenInventor, "/vis/open OI".
|
|
This new form allows the same macro to be used whether one is on Linux
|
|
or Windows (calling OIX on Linux and OIWin32 on Windows).
|
|
o Added "/vis/scene/add/digis" and "/vis/filtering/digi" commands,
|
|
analogous to the already-existing commands "/vis/scene/add/hits" and
|
|
"/vis/filtering/hits". As with hits, it remains the user's
|
|
responsibility to provide the digitisation classes.
|
|
Added method AddCompound(const G4VDigi&) to drivers.
|
|
o Introduced DispatchToModel without 'i_mode'. The archaic form
|
|
G4VTrajectory::DrawTrajectory(i_mode) is replaced by the newer form,
|
|
G4VTrajectory::DrawTrajectory(). 'i_mode' used to be a parameter to
|
|
control whether the trajectory was drawn as a line, a line plus step
|
|
points, or only step points:
|
|
- i_mode > 0 meant draw lines and points, size of points in
|
|
pixels = abs(i_mode)/1000
|
|
- i_mode = 0 meant draw only lines
|
|
- i_mode < 0 meant draw only points, size of points in
|
|
pixels = abs(i_mode)/1000
|
|
Since release 8.1, better control has been available from the command
|
|
"/vis/modeling/trajectories". Since release 5.0, 'i_mode' less than
|
|
1000 has in fact drawn no points and 'i_mode' of 1000 has drawn points
|
|
that were so small (a single pixel wide) that they were overshadowed
|
|
by the trajectory itself except at endpoints of the trajectory or
|
|
where the trajectory made a sharp change of direction.
|
|
Use of 'i_mode' is now trapped and a warning gets printed.
|
|
o Changed order of flags to follow G4UIExecutive.
|
|
o G4VisManager, G4VisExecutive: introduced optional verbosity string
|
|
argument in constructor; made 'fVerbosity' and GetVerbosity() static.
|
|
o Added virtual destructors to fix compilation warnings.
|
|
+ modeling:
|
|
o Added G4DigiModel and G4DigiFilterFactories.
|
|
o Added default colours to G4TrajectoryDrawByParticleID.
|
|
o Replace polyhedra with solids for sections and cutaways.
|
|
o Trap use of 'i_mode' and print warning.
|
|
+ HepRep:
|
|
o Added command "/vis/heprep/renderCylAsPolygons".
|
|
+ gMocren:
|
|
o Removed dependency on G4VisManager. Improved printout.
|
|
+ OpenGL:
|
|
o Some improvements with auto rotation mode.
|
|
o G4OpenGLQtViewer: better inclusion of new tabs in UI part.
|
|

|
|
o Speed improvements for polymarkers (e.g., trajectories).
|
|
o Corrected strdup usage in G4OpenGLViewer.
|
|
o Use generic section and cutaway algorithm.
|
|
o Added protection against multiple repaint call, and protection against
|
|
resizeGl with bad values.
|
|
+ OpenInventor:
|
|
o Added protection against repeated initialisation.
|
|
+ RayTracer:
|
|
o Added missing virtual destructor to G4VRTScanner, G4RTXScanner and
|
|
G4RTSimpleScanner classes.
|
|
|
|
o Data Sets:
|
|
---------
|
|
+ G4EMLOW-6.13:
|
|
o Updated PDF.dat to msc_GS module.
|
|
o New directory and data files needed by ionisation cross section
|
|
models for PIXE; added data tables in the directories uf, kpcsPaul
|
|
and kacsPaul included in the 'pixe' dir.
|
|
o Added 'sigmadiff_cumulated_elastic_e_champion.dat' and
|
|
temporary 'sigma_excitation_e_born.dat' to dna module.
|
|
o Added data files in the penelope module, necessary for
|
|
Penelope08 models for gamma rays.
|
|
+ G4NEUTRONXS-1.0:
|
|
o New data set for Evaluated neutron cross section data on natural
|
|
composition of elements.
|
|
|
|
o Examples:
|

Migration Notes
|
|
---------------
|
|
|
|
o Obsolete classes G4MultipleScattering, G4UrbanMscModel and G4UrbanMscModel2
|
|
are removed in this release; multiple-scattering particle-based processes,
|
|
G4eMultipleScattering, G4hMultipleScattering and G4MuMultipleScattering are
|
|
now mandatory; G4UrbanMscModel93 is now introduced.
|
|
o The visualization trajectory modeling command
|
|
"/vis/modeling/trajectories/create/drawByParticleID"
|
|
used to default all trajectories to grey, with the user having to
|
|
explicitly set any other color code. While the user can still set any
|
|
wished color code, the default has been improved to:
|
|
[e-/red; e+/blue; proton/cyan; gamma/green; neutron/yellow;
|
|
pi+,pi-,pi0/magenta; other/grey].
|
|
o In some examples, visualization that used to draw trajectories as simple
|
|
lines now also draws step points. Users who wish to disable step point
|
|
drawing can do so by commenting out a line in the visualization macro.
|
