0002 Geant4 7.0 - patch-01 Release Notes
0003 -----------------------------------
0004
0005 23 February 2005
0006
0007 List of fixes included in this public patch since the public release 7.0:
0008
0009 o Configuration:
0010 -------------
0011 + Fix in Configure script for unnecessary check on setting of
0012 CLHEP_BASE_DIR to /usr, /usr/local on Linux platforms.
0013
0014 o Event:
0015 -----
0016 + Fixed bug on binning in G4SPSRandomGenerator.
0017 + Fixed reset of histogram energy limits in G4SPSEneDistribution.
0018 + Restored the inheritance to G4VPrimaryGenerator for the
0019 G4GeneralParticleSource class.
0020
0021 o Geometry:
0022 --------
0023 + solids/specific:
0024 o Use new polynom approximations based on new solver based on
0025 Jenkins-Traub algorithm, for twisted-box and twisted-trap.
0026 o Fixed bug in the usage of 'fmod' and adopt special treatment for
0027 'parallel' events in G4TwistedBoxSide and G4TwistedTrapSide.
0028
0029 o Global:
0030 ------
0031 + Added polynom-solver class G4JTPolynomialSolver implementing the
0032 Jenkins-Traub algorithm for real polynomial root finding. To be used
0033 by the twisted-trap shape for precise computation of intersections.
0034
0035 o Interfaces:
0036 ----------
0037 + Minor fix in GNUmakefiles to remove unnecessary definition of G4TMPDIR.
0038
0039 o Parameterisations:
0040 -----------------
0041 + Fix in GFlashHitMaker for treatment of detector sensitivity in the
0042 'gflash' module.
0043
0044 o Particles:
0045 ---------
0046 + Fix in G4UnknownParticle to make it non-static, in order to avoid
0047 unnecessary linking without its definition in the physics list.
0048
0049 o Electromagnetic processes:
0050 -------------------------
0051 + standard:
0052 o Fix in UniversalFluctuation: setting proper constants for probLim
0053 and minimum energy-loss, to improve simulation of energy loss in
0054 thin absorbers.
0055 o Fix in MultipleScattering for function SetSamplez().
0056 o Add extra protection to G4PAIModel to fix cases of NaN observed
0057 in production for ALICE.
0058 + utils:
0059 o Bug fix to avoid crash in the inactivation of e- ionisation.
0060 o Added protection on the value of effective charge to ensure energy
0061 loss for low energy ions.
0062 o Fixing initialisation problem for ion beam observed in CMS.
0063
0064 o Hadronic Processes:
0065 ------------------
0066 + models/chiral_inv_phase_space/body:
0067 o Fixed problem of inconsistency between masses of hadrons and nuclear
0068 fragments and masses defined in Geant4. Conversion of the CHIPS hadrons
0069 to Geant4 secondaries uses now a kinetic energy of the particle, so
0070 Geant4 automatically puts particles on the mass shell.
0071 o Complete usage of the existing nuclear mass approximation of Geant4
0072 [including M(Z,N)_G4>m_p*Z+m_n*N].
0073 o Improvement in G4QEnvironmemt in the usage of FinalStateInteraction
0074 A few cases of the secondary particles below mass shell have been
0075 corrected.
0076
0077 o Management of processes:
0078 -----------------------
0079 + Fix in G4ProcessManager to correct ordering of processes.
0080
0081 o Run:
0082 ---
0083 + Fix in G4RunManager and G4RunManagerKernel to correctly reset static
0084 pointers in the case when RunManager is deleted.
0085 + Updated date to run-manager.
0086
0087 o Visualization:
0088 -------------
0089 + HepRep: minor fix for compilation problem on the obsolete gcc-2.95.2.
0090
0091 o Physics lists:
0092 -------------
0093 + hadronic:
0094 o Fixed compilation problems on gcc-3.4.X compiler series:
0095 Added explicit 'typename' keywords to template class declarations.
0096 Use 'this' pointer to access data-members of base class for
0097 unqualified names in physics-lists inline definitions.
0098
0099 o Examples:
0100 --------
0101 + Updated reference outputs.
0102 + electromagnetic/TestEm1
0103 o HistoManager: added protection for the creation of the analysis
0104 factory. File extension is fileType.
0105 o HistoMessenger: new command 'setFileOption'.
0106 + electromagnetic/TestEm3
0107 o Fix in SteppingAction to correct the energy flow.
0108 o Added new macros linac.mac and geant3/linac.dat.
0109 + novice/N02
0110 o PhysicsList: added usage of G4StepLimiter (as commented line).
0111 + novice/N03
0112 o Fix in SteppingAction: sum stepLength of charged particle even
0113 if edep=0.
