| 2 | + Geant4 8.0 - patch-01 Release Notes |
| 3 | + ----------------------------------- |
| 4 | + |
| 5 | + 10 February 2006 |
| 6 | + |
| 7 | +List of fixes included in this public patch since the public release 8.0: |
| 8 | + |
| 9 | + o Digits & Hits: |
| 10 | + ------------- |
| 11 | + + Added missing methods in G4VDigiCollection and G4TDigiCollection. |
| 12 | + Addresses problem report #786. |
| 13 | + |
| 14 | + o Geometry: |
| 15 | + -------- |
| 16 | + + divisions |
| 17 | + o Added missing setting of mother-logical pointer in constructors of |
| 18 | + G4PVDivision. Fixes problem report #829. |
| 19 | + o Added missing checks for illegal constructs of G4PVDivision (NULL |
| 20 | + pointer to mother logical and self-placement). |
| 21 | + o Fixed check for generic construct in G4ParameterisationPolycone and |
| 22 | + G4ParameterisationPolyhedra: allow it for the automatic replicated |
| 23 | + instance. |
| 24 | + o Cache information about axis of division and provided accessor method |
| 25 | + GetDivisionAxis() in G4PVDivision. |
| 26 | + + navigation |
| 27 | + o Addressing problem with convergence in LocateIntersectionPoint() |
| 28 | + of G4PropagatorInField. The problem, identified by Atlas, was |
| 29 | + observed when requesting high precision, i.e. small values of |
| 30 | + eps_min/max, delta_one_step, due to need for small delta_intersection. |
| 31 | + Increased maximum iterations (from 100 to 10000) until correct |
| 32 | + information can be return an Exception is thrown in case of too many |
| 33 | + iterations; a warning is thrown in case over 1000 iterations. |
| 34 | + + solids/BREPS |
| 35 | + o Use explicit 'HepGeom' namespace for 'Identity', to allow for |
| 36 | + porting on Windows/VC++ when using CLHEP-2.0.X. |
| 37 | + + solids/CSG |
| 38 | + o G4Sphere: fixed bug in DistanceToOut() for theta intersections. |
| 39 | + Fixes problem report #830. |
| 40 | + + solids/specific |
| 41 | + o Fixed visibility of soft edges for visualization of twisted solids. |
| 42 | + o G4TwistedTubs and G4VTwistedFaceted::CreatePolyhedron(): changed |
| 43 | + parameterised polyhedron mesh approximation in terms of |
| 44 | + G4Polyhedron::GetNumberOfRotationSteps(). |
| 45 | + o Fixes in G4EllipticalCone: |
| 46 | + - Changed GetPointOnSurface(), which was not uniform in endcaps. |
| 47 | + - Bug fix in Inside(), which was not correct for the elliptic mantel. |
| 48 | + Made test similar as in G4EllipticTube. |
| 49 | + - Several fixes in DistanceToIn/Out() resolving problems of looping |
| 50 | + events. |
| 51 | + + volumes |
| 52 | + o G4AssemblyVolume: fixed initialisation of names for placed volumes |
| 53 | + which was corrupted after migration to <sstream> as side effect. |
| 54 | + |
| 55 | + o Particles: |
| 56 | + --------- |
| 57 | + + Bug fix for G4ParticleDefinition, was causing improper behavior of |
| 58 | + GetAtomicNumber() method for ions. Fixes problem report #827. |
| 59 | + |
| 60 | + o Electromagnetic processes: |
| 61 | + ------------------------- |
| 62 | + + standard: |
| 63 | + o Fix in G4PolarizedComptonScattering, returning PostStepDoIt() |
| 64 | + for G4ComptonScattering52. Fixes problem report #478. |
| 65 | + |
| 66 | + o Hadronic Processes: |
| 67 | + ------------------ |
| 68 | + + management: |
| 69 | + o G4HadronicProcess: fixed problem report #611. Problems caused when |
| 70 | + hadronic interactions reset stopButAlive particle to Alive. |
| 71 | + o Added diagnostics when hadronic exceptions occur in G4HadronicProcess |
| 72 | + and G4EnergyRangeManager. |
| 73 | + + models/binary_cascade: |
| 74 | + o Fixed problem report #794. Projectile nucleus needs to be centered. |
| 75 | + + models/chiral_inv_phase_space/body: |
| 76 | + o Fixed trivial compilation warning. |
| 77 | + + models/de_excitation: |
| 78 | + o G4NuclearLevelManager: print a warning if no data file is present. |
| 79 | + Addressed problem report #814. |
| 80 | + o G4ParaFissionModel: fix for compilation error, following problem |
| 81 | + report #817. |
| 82 | + + models/neutron_hp: |
| 83 | + o Fixes core dump observed when neutron energy is close to 20 MeV. |
| 84 | + + models/radioactive_decay |
| 85 | + o G4NuclearDecayChannel::BetaDecayIt(): check for negative sqrt() |
| 86 | + argument in 'daughtermomentum[1]'. Fixes problem report #822. |
| 87 | + + stopping: |
| 88 | + o Set process type to be 'fHadronic'. Was not set previously. |
| 89 | + + util: |
| 90 | + o G4ReactionDynamics: added array bounds protection in TwoCluster(). |
| 91 | + |
| 92 | + o Processes cuts: |
| 93 | + -------------- |
| 94 | + + Fix in G4VRangeToEnergyConverter::Convert() to recalculate the energy |
| 95 | + loss table if new elements are added. Fixes problem report #831. |
| 96 | + |
| 97 | + o Track: |
| 98 | + ----- |
| 99 | + + G4ParticleChangeForRadDecay is now derived from G4ParticleChangeForDecay. |
| 100 | + |
| 101 | + o Transportation: |
| 102 | + -------------- |
| 103 | + + G4Transportation: the particle's charge is now taken from the dynamic |
| 104 | + particle, so that it can take into account changes from the interaction |
| 105 | + of an ion with matter (eg stripping e-). |
| 106 | + + Corrected problem with suspended tracks, addressing problem report #802. |
| 107 | + Added StartTracking() method which takes over responsibility to clear |
| 108 | + the state for a new track, and to message other relevant component to |
| 109 | + clear their state. |
| 110 | + |
| 111 | + o Visualization: |
| 112 | + ------------- |
| 113 | + + management: |
| 114 | + o Fixed bug that omits geometry volumes from file-based visualization |
| 115 | + drivers for first /run/beamOn. |
| 116 | + o Added friend status for ray-tracer. |
| 117 | + + RayTracer: |
| 118 | + o Fix behavior of messengers when RayTracerX is used. |
| 119 | + o Allow for multiple ray tracers. |
| 120 | + o Separated out the original ray tracer to be used by viewers. |
| 121 | + |
| 122 | + o Data: |
| 123 | + ---- |
| 124 | + + New data set for high-precision neutron processes G4NDL-3.8 |
| 125 | + o Added Gadorinium data (source ENDF/B-VI). |
| 126 | + o Replaced: Inelastic/CrossSection/17_nat_Chlorine and |
| 127 | + Inelastic/F10/28_62_Nickel (source ENDF/B-VI). |
| 128 | + o Removed: Inelastic/CrossSection/32_70|72|73|74|76_Germanium |
| 129 | + |
| 130 | + o Examples: |
| 131 | + -------- |
| 132 | + + Updated reference outputs. |
| 133 | + + extended/electromagnetic/TestEm7 |
| 134 | + o Trivial fix of memory leak. |
| 135 | + + extended/medical/GammaTherapy |
| 136 | + o Substituted PreciseRange with CSDARange. |
