o G4IntersectingVone: added protection against NaN in LineHitsCone1()
in case of configurations where a conic section becomes a tube.
Added kCarTolerance in definition of "low" and "high" cone limits
in R and in Z in order to protect against numerical errors; this
fixes cases of DistanceToIn(p,v) returning 'kInfinity' when p+t*v
cross intersection between two cones.
o G4EllipticalCone: removed some debug printouts.
o G4Hype: refined polyhedron representation for correct visualization
of the shape.
o Global:
------
+ Introduced inclusion of <cstring> and <climits> in G4String.hh and
templates.hh respectively for porting on gcc-4.3.0 compiler.
+ Cleared compilation warnings detected on gcc-4.3.0
+ Removed useless specification of units in implementation of
G4GeometryTolerance::SetSurfaceTolerance().
+ Changed date for patch-02 to release 9.1.
o Graphics Representations:
------------------------
+ Added G4Hype representation to HepPolyhedron and G4Polyhedron.
+ Added inclusion of <cstdlib> in HepPolyhedron.cc for porting on
gcc-4.3.0 compiler.
o Materials:
---------
+ G4NistMaterialBuilder: using correct dimension for the density for
ConstructNewMaterial() methods.
+ G4Material: improved printout in error conditions by specifying the
name of the material affected.
o Particles:
---------
+ G4ParticleTable: fixed implementation of methods Remove() and
RemoveAllParticles() so that particle definition objects are properly
deleted when invoking these methods between runs. It's user's
responsibility to delete dynamically instantiated particle objects.
Added method DeleteAllParticles() to remove and delete all particles
in the list. Addressing problem report #1007.
+ Fixed bugs in G4Iontable::Remove() and G4ShortLivedTable::Remove().
o Physics Lists:
-------------
+ Fixed deletion using uninitialized pointers in FTF-BIC, for classes
HadronPhysicsFTF_BIC, G4FTFBinaryNeutronBuilder and G4LEPNeutronBuilder.
o Electromagnetic Processes:
-------------------------
+ Standard:
o G4UrbanMscModel90, G4UrbanMscModel: fixed asymmetry of lateral
displacement.
o G4ionIonisation: adopt 'linLossLimit' 0.15 as it was originally in 9.1.
o G4IonFluctuations: fixed discontinuity of width correction factor
for small velocities and added a protection to its value
(factor>1), which fixes very long alpha events.
+ Utils:
o G4EmCorrections: set finite size correction to zero (provides flat
distribution of vertex detector response for high energy hadrons).
o G4ionEffectiveCharge: minor change of numerical constants to provide
continuous change of charge versus energy.
o Hadronic Processes:
------------------
+ Cleared most compilation warnings detected on gcc-4.3.0.
+ cross_sections:
o G4NeutronInelasticCrossSection: fixed bug which used to return zero
cross section for 3He.
o G4TripathiLightCrossSection: fixed bug in method IsApplicable() to
use GetN() instead of GetA() for target.
o Added capability to use element-based cross section data
sets if no isotope-based ones are available. This is required to
get the HP neutron code to work within the cross section framework
introduced in version 9.0. Added internal method to class
G4CrossSectionDataStore.
+ models/cascade:
o Added Coulomb barrier in G4EquilibriumEvaporator.
o Changed pp, nn total cross section parameterization in class
G4CascadSpecialFunctions to more closely reflect the PDG values;
fixed cross section bug responsible for returning low or zero total
cross sections for pi-p, pi+n, np, and pi0 interactions.
+ models/chiral_inv_phase_space:
o Modified G4QElasticCrossSection to fix problem with quasi-elastic.
When run together with elastic, the parameters to sample T were not
updated, this fix is to always update these.
o Fixed case of exceeded boundary bounds in G4QCollision.
o Check on tolerance is replaced by check on exact equality for fixing
event reproducibility.
+ models/coherent_elastic:
o G4HadronElastic: added extra protection against precision lost
when projectile almost lost kinetic energy; set 'lowestEnergyLimit'
to be 1.e-6*eV (was 0.0).
Added extra protection: if sampled t out of the physics range then
no scattering.
o G4UHadronElasticProcess: call to G4QElasticCrossSection with option
"false", so parameters for sampling of scattering are precalculated.
+ models/neutron_hp:
o Fix against cases of division by zero.
o Fixed erroneous condition in G4NeutronHPContAngularPar.
o To increase performance, checking point of "neglecting doppler
broadening" flag is changed from GetCrossSection() method to
BuildPhysicsTable().
+ models/theo_high_energy:
o Added missing Fermi momentum to quasi elastic scattering.
+ stopping:
o G4MuMinusCaptureCascade: fixed case of NaN value in bound muon decay.
o Generic Processes:
-----------------
+ Decay:
o Added protection to properly handle shortlived particles with finite
pre-assigned proper time.
+ Management:
o Fixed bug related to invoking ResetNumberOfInteractionLengthLeft()
at the zero length step
o Allow zero mean free path for PostStepDoIt().
+ Parameterisation:
o Cleared compilation warnings detected on gcc-4.3.0.
o Run:
---
+ Added G4Transportation to shortlived particles in G4VUserPhysicsList
in order to fix problem of non-assigned process for shortlived particle
decay detected in CMS.
o Examples:
--------
+ advanced/underground_physics:
o Fixed mis-sized arrays 'ring_phys_gas' and 'ring_phys_liq';
both were less than the utilized size.
+ extended/field/field02:
o Fixed setup to correctly handle electric field.
+ extended/field/field04:
o Fix to avoid error for invalid rotation specification
in F04DetectorConstruction::stringToRotationMatrix().

Geant4 9.1 - patch-03 Release Notes
-----------------------------------
12 September 2008
List of fixes included in this public patch since the public release 9.1.p02:
o Configuration:
-------------
+ architecture.gmk: removed obsoled DOM library from GDMLIBS; resolving
run-time problems on Windows systems.
+ liblist.c: removed C++ style comments; resolving compilation problems
on legacy SUN-CC compiler.
o Digits_Hits:
-----------
+ Fixed a bug in G4ScoringBox for the use of G4PVDivision
and G4VScoreWriter for indexing scheme in GetIndex() method.
o Event:
-----
+ Provided accessors to G4SPSAngDistribution.
Addressing problem report #1013.
+ Cleared gcc-4.3.0 compilation warnings in G4SPSEneDistribution.
o G3toG4:
------
+ GNUmakefile: workaround for renewing Fortran objects in 'lib' target
before re-build of libraries.
o Geometry:
--------
+ divisions:
o Corrected initialisation for 'fnReplicas' and 'fwidth' data members
in CheckAndSetParameters(), to make use of precomputed values retrieved
from concrete parameterisations; simplified method signature.
o Corrected error print-out in CheckNDivAndWidth() method in
G4VDivisionParameterisation class.
+ management:
o G4LogicalVolume, G4LogicalVolumeStore: corrected logic for the deletion
of the root-region volumes, adding locking mechanism and automatically
de-registering the world default root-region.
Simplified Clean() method in the store, by removing unused and
unnecessary default flag for logical-volumes notification.
o Reinstated update of materials in G4Region::RemoveRootLogicalVolume()
to correct handling individual removal of root-region volumes and
restore proper setup state.
o G4Region: changed condition inside ScanVolumeTree() to check for the
existence of a valid material-scanner pointer to apply the material
scan instead of using the flag for nested structures.
o G4GeometryManager: do not apply optimisation on the current volume if
it has been defined as a regular structure.
Addresses problem report #990.
o G4VSolid: promote copy-constructor and assignment operator to public
to cope with specific use-case in ATLAS (see problem report #1023).
+ navigation:
o G4PropagatorInField: correction to LocateIntersectionPoint() algorithm
to ensure that endpoints are not further apart in space than on the
curve due to different errors in the integration.
Resolves rare error conditions in ATLAS production.
+ solids/CSG:
o G4Sphere: fixed bug in DistanceToOut(p, v, ...) for normal 'fSTheta'
greater than 90*deg, and use of tangent giving negative value.
Fixed calculation of roots in DistanceToOut(p,v,...) for theta-conical
surface interserctions and for sTheta<=90 degree intersection.
Addresses issue reported when running PET application with optical
photons about mis-computation of distance on half-sphere constructs,
and later also reported in problem report #1022.
o G4Tubs: fix in DistanceToIn(p,v, ...) in case of point on surface with
very small tangent direction; now returning kInfinity and no longer
zero. It fixes rare observed cases of zero value returned by both
DistanceToIn() and DistanceToOut(), causing stuck tracks with zero
step length.
+ solids/specific:
o G4ExtrudedSolid: fix in polygon decomposition; systematically use
half kCarTolerance instead of kCarTolerance; added solid name in the
error messages coming from fatal exceptions.
Added missing 'std' namespace to standard mathematical function calls.
o G4Paraboloid: revised DistanceToOut(p,v,...) in answer to problem
report #1015. Fixed precision problem when solving quadratic equation;
apply comparison with kCarTolerance and not with zero; fixed logic
problem in algorithm for points on surface and direction inside,
relative to directions along Z, (0,0,Vz).
o G4VFacet: corrected increment of indeces in operator==().
Addressing problem report #1024.
o Global:
------
+ Corrected signature of G4SwapPtr() to use reference of pointers as
arguments.
+ Changed date for patch-03 to release 9.1.
o Interfaces:
----------
+ Replaced calls to exit() with G4Exception wherever applicable.
o Materials:
---------
+ G4Element: extended printout of errors and warnings; added more safe
check of consistency between Z and A in construction.
+ G4Material: improved errors printout.
o Hadronic Processes:
------------------
+ models/coherent_elastic:
o G4HadronElastic: added protection inside LElastic algorithm against
cases of t>tmax (outside kinematically allowed 4-momentum transfer).
+ models/lll_fission:
o Replaced usage of exit() with G4Exception in G4fissionerr.
+ models/high_energy:
o In G4HEInelastic: fixed bug in HighEnergyCascading() and
MediumEnergyCascading() for momentum sampling, responsible for
oscillatory behavior in spectrum.
In TuningOfHighEnergyCascade(), removed abnormally high pt secondaries
due to incident strange particles by prohibiting the assignment of
leading particle to anything that goes backward in the CM frame.
Replaced usage of exit() with G4Exception in Factorial() method.
In NBodyPhaseSpace(), removed error message "total mass > total energy"
and replaced with message only when verbosity is > 1.
+ models/parton_string/diffraction:
o Fixed compilation warnings for unused variables in G4FTFModel.
+ models/pre_equilibrium:
o Fixed cases of floating point overflow when using pre-compound in
combination with binary-cascade; reviewed algorithm in method
G4PreCompoundEmission::rho().
+ util:
o G4ReactionDynamics::GenerateXandPt(): fixed bug in momentum bin
responsible for causing oscillatory behavior in spectrum.
Replaced usage of exit() with G4Exception.
o Generic Processes:
-----------------
+ Management:
o Fixed un-necessary double deletion/creation of vector in operator=()
in G4ProcessVector.
o Fixed compilation warning on messenger.
o Run:
---
+ G4RunManagerKernel: avoid deletion of default root-region which is now
taken care by the geometry stores. It resolves the ambiguity of explicitly
avoiding the de-registration and deletion of the default root-region by
the stores and eliminates the limitation of forcing the world logical
volume being the first registered in the logical-volumes store.
+ Invoke G4Particle::DeleteAllParticles() in the destructor of
G4VUserPhysicsList to clear memory leak at application closure.
o Tracking:
--------
+ Fix in G4SteppingManager to properly update 'fTouchableHandle' data
member. Addresses problem report #1009.
o Examples:
--------
+ advanced/air_shower:
o Adjusted range of optical properties tables in DetectorConstruction;
Added check of optical photon energy in PrimaryGeneratorAction;
Cerenkov process attached to all applicable particles;
Modified Visualisation.mac and UltraMacro.mac macros.
o Corrected a parameter in the DetectorConstruction to fix a
segmentation due to a non correct definition of the refraction index
of the Quartz.
o Implemented access to private data members of DetectorConstruction
through accessors.
o Fixed a compilation warning in AnalysisManager.
+ advanced/brachytherapy:
o Fixed compilation warning in AnalysisManager. Fixed bad type assignment.
o Activated generation of histogram files for output.
+ advanced/gammaray_telescope:
o Fixed problems in compilation.
+ advanced/lAr_calorimeter:
o Fixed compilation warning in AnalysisManager.
+ advanced/Rich:
o Fixed compilation errors and removed warnings.
+ advanced/Tiara:
o Fixed compilation errors.
+ extended/exoticphysics/monopole:
o Fixed compilation warnings.
+ extended/medical/DICOM:
o Bug fix in DicomNestedPhantomParameterisation in calculating the cell
copy-number; now fixing the material assignments.
o Set default cut to 1 mm to reduce physics content and enhance tracking
performance.
o Corrected direction and position of primary particles to better
traverse the DICOM voxels.
