16 | o Event: (*) |
---|
17 | ----- |
---|
18 | + G4ParticleGun: |
---|
19 | o Added class member 'particle_momentum' and method |
---|
20 | SetParticleMomentum(). |
---|
21 | o Added private copy constructor and =, ==, += operators to |
---|
22 | Addressing problem report #984. |
---|
23 | + Modified G4SPSEneDistribution to adress problem report #988. |
---|
24 | |
---|
25 | o Geometry: |
---|
26 | -------- |
---|
27 | + management: (*) |
---|
28 | o Fixed typo in forcing minimum number of points in method |
---|
29 | G4VSolid::EstimateSurfaceArea(). Addresses problem report #981. |
---|
30 | + navigation: (*) |
---|
31 | o G4PropagatorInField: |
---|
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. |
