| 9 | o Error Propagation:
|
|---|
| 10 | -----------------
|

|
|---|
| 18 | + G4ParticleGun:

| 32 | - Fixes for compilation of code under G4DEBUG_FIELD
|
|---|
| 33 | (problem report #982).
|
|---|
| 34 | - Changed condition for 'ReEstimationEndPoint' in order to better
|
|---|
| 35 | handle very strict parameters of propagation. Also added more
|
|---|
| 36 | verbosity in case of error for negative step.
|
|---|
| 37 | Fixes rare problem observed in production by ATLAS.
|
|---|
| 38 | - Added extra check of method LocateIntersectionPoint() arguments.
|
|---|
| 39 | + solids/Boolean: (*)
|
|---|
| 40 | o Boosted performance for response of Inside() for G4SubtractionSolid
|
|---|
| 41 | and G4UnionSolid according to suggestion in problem report #979.
|
|---|
| 42 | + solids/BREPS: (*)
|
|---|
| 43 | o Fixed bug in G4BREPSolidPolyhedra::DistanceToOut() for cases of
|
|---|
| 44 | particle passing the border of two touching surfaces.
|
|---|
| 45 | o G4BREPSolidBox: fixed problem in the constructor in definition of
|
|---|
| 46 | the side for the normal to surface.
|
|---|
| 47 | + solids/CSG: (*)
|
|---|
| 48 | o G4Torus:
|
|---|
| 49 | - Fixed bug in CalculateExtent() for case of non-rotated full-Phi
|
|---|
| 50 | torus definition: added protection against negative value for sqrt()
|
|---|
| 51 | and corrected formula for 'delta'.
|
|---|
| 52 | Fixes problem of NaN detected in initialisation by CMS.
|
|---|
| 53 | - Fixed bug in SolveNumericJT(): corrected handling of complex roots.
|
|---|
| 54 | Addresses problem report #969.
|
|---|
| 55 | o Fixed problem of undefined side for valid surface normal in case of
|
|---|
| 56 | 'Phi' section and direction through the center of either a G4Tubs or
|
|---|
| 57 | G4Cons shape.
|
|---|
| 58 | + solids/specific: (*)
|
|---|
| 59 | o Removed debug printout in G4Polycone::GetPointOnCone().
|
|---|
| 60 |
|
|---|
| 61 | o Global:
|
|---|
| 62 | ------
|
|---|
| 63 | + Changed date for patch-02 to release 9.0.
|
|---|
| 64 |
|
|---|
| 65 | o Management Processes:
|
|---|
| 66 | --------------------
|
|---|
| 67 | + G4WrapperProcess: fixed double definition of method PreparePhysicsTable()
|
|---|
| 68 | in the header and moved inline implementations of virtual methods to
|
|---|
| 69 | source file.
|
|---|
| 70 |
|
|---|
| 71 | o Hadronic Processes:
|
|---|
| 72 | ------------------
|
|---|
| 73 | + management: (*)
|
|---|
| 74 | o G4HadronicProcess::FillTotalResult(): fix addressing problem report
|
|---|
| 75 | #967, replaced call to 'aT.GetGlobalTime()' with an internal variable.
|
|---|
| 76 | + models/cascade:
|
|---|
| 77 | o Fixed angular distribution for nucleon-nucleon elastic scattering
|
|---|
| 78 | above 2.8 GeV.
|
|---|
| 79 | + models/chiral_inv_phase_space: (*)
|
|---|
| 80 | o Fixed problem of non-reproducibility induced by G4QElasticCrossSection
|
|---|
| 81 | and G4StringChipsInterface.
|
|---|
| 82 | o Reduced memory allocation induced by use std::deque collection in
|
|---|
| 83 | G4QHadron class; temporary workaround by replacing it with std::list.
|
|---|
| 84 | + models/high_energy: (*)
|
|---|
| 85 | o G4HEInelastic::TuningOfHighEnergyCascading(): fixed incorrect
|
|---|
| 86 | assignment of leading particle to low energy backward nucleons and
|
|---|
| 87 | fragments. This bug caused high energy backward particles to be
|
|---|
| 88 | emitted from high energy collisions.
|
|---|
| 89 | o G4HEPionMinusInelastic: fixed incorrect 'Imax' in sampling of charge
|
|---|
| 90 | exchange.
|
|---|
| 91 | + stopping: (*)
|
|---|
| 92 | o G4StopElementSelector: fixed typo in Primakoff formula for
|
|---|
| 93 | capture velocity.
|
|---|
| 94 | o G4MuonMinusCaptureAtRest: fixed old memory leak.
|
|---|
| 95 | o Removed old-style copyright from all headers and fixed Software
|
|---|
| 96 | Reference Manual tags.
|
|---|
| 97 |
|
|---|
| 98 | o Examples:
|
|---|
| 99 | --------
|
|---|
| 100 | + advanced/underground_physics:
|
|---|
| 101 | o Corrected micrometer unit in macros from mum to um (old bug since 8.2).
|
|---|
| 102 |
|
|---|
| 103 |
|
|---|
| 104 | (*) Fixes also included in the patched release 8.3.p02.
