|
|
|

|
+ In G4UIQt, replaced use of G4int by int in QT signal/slots.
|
|
|
|
o Particles:
|
|
---------
|
|
+ Updated mean lifetime values of G4XicZero and G4AntiXicZero according to
|
|
values in PDG-2022. Corrected values for G4[Anti]OmegacZero.
|
|
|
|
o Persistency:
|
|
-----------
|
|
+ gdml
|
|
o Fixed cases of failure in exporting tessellated solids: make
|
|
G4ThreeVectorCompare:operator(v1,v2) obey the strict weak ordering
|
|
requirements.
|
|
|
|
o Physics Lists:
|
|
-------------
|
|
+ builders
|
|
o G4HadronicBuilder: fixed bug in method BuildKaonsFTFQGSP_BERT().
|
|
|
|
o Processes - Electromagnetic:
|
|
---------------------------
|
|
+ highenergy
|
|
o G4GammaConversionToMuons: fixed FPE exception in compound, when
|
|
selecting element and addressed cross-section factor issue responsible
|
|
for differences in muon/pion production.
|
|
Addressing problem report #2543.
|
|
+ muons
|
|
o G4MuBremsstrahlung, G4MuPairProduction: fixed setting of Spline flag,
|
|
which was lost for mu-, pi-, K-, pbar dedx and range tables; the
|
|
problem was mostly observed for mu- with momentum ~50 MeV/c, ~5 %
|
|
biased range. Addressing problem report #2531.
|
|
o G4MuBetheBlochModel: enabled option to use angular generator for
|
|
sampling of delta-electron direction.
|
|
o G4MuIonisation: implemented full schema of selection of the model of
|
|
energy loss fluctuation.
|
|
+ standard
|
|
o G4WentzelOKandVIxSection: fixed numeric instability for the extreme
|
|
case of very small kinetic energy (< 1 eV). Improved comments and
|
|
fixed single scattering per region. Addressing problem report #2530.
|
|
o G4LinhardSorensenModel: updating effective charge of an ion at each
|
|
step of simulation or at each call to G4EmCalculator; added extra
|
|
protection and improved debug printout.
|
|
Avoid use of ICRU73 data for projectile Z>80.
|
|
+ utils
|
|
o G4EmExtraParameters: fixed AddPAIModel() method and improved comments.
|
|
o G4EmExtraParametersMessenger: fixed broadcasting.
|
|
o Allow "/process/em/QuantumEntanglement" UI command in G4State_Idle.
|
|
o Fixed Coverity warning in G4VEnergyLossProcess.
|
|
o G4EmTableUtil: fixed verbose output and class comments.
|
|
o G4LossTableManager: improved debug printout and removed unused code.
|
|
o Fixes to G4TransportationWithMsc: protected code for MultipleScattering;
|
|
fixed type of particle change.
|
|
|
|
o Processes - Hadronic:
|
|
--------------------
|
|
+ models/cascade
|
|
o G4BigBanger: added protection in the method generateBangInSCM() to
|
|
avoid very rare cases of unphysical negative energy of one of the
|
|
secondaries produced by the Bertini model.
|
|
The problem was reported by ATLAS in production runs based on
|
|
release 10.6; the secondaries with negative (both total and kinetic)
|
|
energy were always neutrons, produced by the internal Bertini nuclear
|
|
de-excitation, after the intra-nuclear cascade.
|
|
+ models/inclxx
|
|
o G4INCLNNToNLK2piChannel: fixed bug in the method fillFinalState().
|
|
+ models/particle_hp
|
|
o Added G4ParticleHPNucLevel, new data structure for nuclear levels.
|
|
o G4ParticleHPDeExGammas: rewritten in order to avoid usage of C-arrays
|
|
and use std::vector instead; public interfaces are unchanged; if in DB
|
|
probability of decay for a give level is zero; it is substituted to
|
|
1.e-6.
|
|
o G4ParticleHPInelasticBaseFS, G4ParticleHPInelasticCompFS: gamma
|
|
cascade sampling is checked and simplified (removed unnecessary
|
|
computations).
|
|
+ util
|
|
o G4Fragment: replaced G4HadronicException with standard G4Exception.
|
|
|
|
o Processes - Parameterisation:
|
|
----------------------------
|
|
+ Added missing virtual destructor to G4VFastSimSensitiveDetector.
|
|
|
|
o Run:
|
|
---
|
|
+ Removed mistyped method declaration GetMasterTheadId() in G4MTRunManager.
|
|
|
|
o Examples:
|
|
--------
|
|
+ extended/geometry/vecGeomNavigation
|
|
o Stick to G4VecGeomNav package v0.2.1, compatible with VecGeom v1 series.
|
|
|
