| 2 | + Geant4 7.0 - patch-01 Release Notes |
| 3 | + ----------------------------------- |
| 4 | + |
| 5 | + 23 January 2005 |
| 6 | + |
| 7 | +List of fixes included in this public patch since the public release 7.0: |
| 8 | + |
| 9 | + o Configuration: |
| 10 | + ------------- |
| 11 | + + Fix in Configure script for unnecessary check on setting of |
| 12 | + CLHEP_BASE_DIR to /usr, /usr/local on Linux platforms. |
| 13 | + |
| 14 | + o Event: |
| 15 | + ----- |
| 16 | + + Fixed bug on binning in G4SPSRandomGenerator. |
| 17 | + + Fixed reset of histogram energy limits in G4SPSEneDistribution. |
| 18 | + + Restored the inheritance to G4VPrimaryGenerator for the |
| 19 | + G4GeneralParticleSource class. |
| 20 | + |
| 21 | + o Geometry: |
| 22 | + -------- |
| 23 | + + solids/specific: |
| 24 | + o Use new polynom approximations based on new solver based on |
| 25 | + Jenkins-Traub algorithm, for twisted-box and twisted-trap. |
| 26 | + o Fixed bug in the usage of 'fmod' and adopt special treatment for |
| 27 | + 'parallel' events in G4TwistedBoxSide and G4TwistedTrapSide. |
| 28 | + |
| 29 | + o Global: |
| 30 | + ------ |
| 31 | + + Added polynom-solver class G4JTPolynomialSolver implementing the |
| 32 | + Jenkins-Traub algorithm for real polynomial root finding. To be used |
| 33 | + by the twisted-trap shape for precise computation of intersections. |
| 34 | + |
| 35 | + o Interfaces: |
| 36 | + ---------- |
| 37 | + + Minor fix in GNUmakefiles to remove unnecessary definition of G4TMPDIR. |
| 38 | + |
| 39 | + o Parameterisations: |
| 40 | + ----------------- |
| 41 | + + Fix in GFlashHitMaker for treatment of detector sensitivity in the |
| 42 | + 'gflash' module. |
| 43 | + |
| 44 | + o Particles: |
| 45 | + --------- |
| 46 | + + Fix in G4UnknownParticle to make it non-static, in order to avoid |
| 47 | + unnecessary linking without its definition in the physics list. |
| 48 | + |
| 49 | + o Electromagnetic processes: |
| 50 | + ------------------------- |
| 51 | + + standard: |
| 52 | + o Fix in UniversalFluctuation: setting proper constants for probLim |
| 53 | + and minimum energy-loss, to improve simulation of energy loss in |
| 54 | + thin absorbers. |
| 55 | + o Fix in MultipleScattering for function SetSamplez(). |
| 56 | + o Add extra protection to G4PAIModel to fix cases of NaN observed |
| 57 | + in production for ALICE. |
| 58 | + + utils: |
| 59 | + o Bug fix to avoid crash in the inactivation of e- ionisation. |
| 60 | + o Added protection on the value of effective charge to ensure energy |
| 61 | + loss for low energy ions. |
| 62 | + o Fixing initialisation problem for ion beam observed in CMS. |
| 63 | + |
| 64 | + o Hadronic Processes: |
| 65 | + ------------------ |
| 66 | + + models/chiral_inv_phase_space/body: |
| 67 | + o Fixed problem of inconsistency between masses of hadrons and nuclear |
| 68 | + fragments and masses defined in Geant4. Conversion of the CHIPS hadrons |
| 69 | + to Geant4 secondaries uses now a kinetic energy of the particle, so |
| 70 | + Geant4 automatically puts particles on the mass shell. |
| 71 | + o Complete usage of the existing nuclear mass approximation of Geant4 |
| 72 | + [including M(Z,N)_G4>m_p*Z+m_n*N]. |
| 73 | + o Improvement in G4QEnvironmemt in the usage of FinalStateInteraction |
| 74 | + A few cases of the secondary particles below mass shell have been |
| 75 | + corrected. |
| 76 | + |
| 77 | + o Management of processes: |
| 78 | + ----------------------- |
| 79 | + + Fix in G4ProcessManager to correct ordering of processes. |
| 80 | + |
| 81 | + o Run: |
| 82 | + --- |
| 83 | + + Fix in G4RunManager and G4RunManagerKernel to correctly reset static |
| 84 | + pointers in the case when RunManager is deleted. |
| 85 | + + Updated date to run-manager. |
| 86 | + |
| 87 | + o Visualization: |
| 88 | + ------------- |
| 89 | + + HepRep: minor fix for compilation problem on the obsolete gcc-2.95.2. |
| 90 | + |
| 91 | + o Physics lists: |
| 92 | + ------------- |
| 93 | + + hadronic: |
| 94 | + o Fixed compilation problems on gcc-3.4.X compiler series: |
| 95 | + Added explicit 'typename' keywords to template class declarations. |
| 96 | + Use 'this' pointer to access data-members of base class for |
| 97 | + unqualified names in physics-lists inline definitions. |
| 98 | + |
| 99 | + o Examples: |
| 100 | + -------- |
| 101 | + + Updated reference outputs. |
| 102 | + + electromagnetic/TestEm1 |
| 103 | + o HistoManager: added protection for the creation of the analysis |
| 104 | + factory. File extension is fileType. |
| 105 | + o HistoMessenger: new command 'setFileOption'. |
| 106 | + + electromagnetic/TestEm3 |
| 107 | + o Fix in SteppingAction to correct the energy flow. |
| 108 | + o Added new macros linac.mac and geant3/linac.dat. |
| 109 | + + novice/N02 |
| 110 | + o PhysicsList: added usage of G4StepLimiter (as commented line). |
| 111 | + + novice/N03 |
| 112 | + o Fix in SteppingAction: sum stepLength of charged particle even |
| 113 | + if edep=0. |
| 114 | + |
