Geant4 9.4 - patch-04 Release Notes
|
|
-----------------------------------
|
|
|
|
13 April 2012
|
|
|
|
List of fixes included in this public patch since the public release 9.4.p03:
|
|
|
|
o Geometry:
|
|
--------
|
|
+ Magnetic Field:
|
|
o G4FieldTrack: added inline method to set the Rest Mass. Needed in
|
|
order to reset this and keep reuse the same G4FieldTrack in a
|
|
client across tracks.
|
|
|
|
o Global:
|
|
------
|
|
+ G4Pow: reduced vector for factorial from 512 to 170 (result should be
|
|
below DBL_MAX). Fixed computation of log(factorial).
|
|
Added protection in powN() method for high exponent values.
|
|
+ Changed date for patch-04 to release 9.4.
|
|
|
|
o Electromagnetic Processes:
|
|
-------------------------
|
|
+ Standard:
|
|
o G4UrbanMscModel92, G4UrbanMscModel93, G4UrbanMscModel95: added
|
|
protection against big scattering angles for e+- (E > 20 MeV); the
|
|
protection cuts tail of scattering angles to avoid artificial
|
|
scattering of high energy e+-.
|
|
o G4WentzelVIModel: fixed algorithm for sampling of single scattering
|
|
along step.
|
|
o G4WentzelOKandVIxSection: fixed incorrect angular limit for protons.
|
|
Fixed screening function for low Z materials.
|
|
o G4UniversalFluctuation: fixed sampling at small steps (below 10 um)
|
|
in heavy media about shift in range of 3 MeV muons.
|
|
o G4eCoulombScatteringModel: fixed initialisation of base class data
|
|
in method SetLowEnergyLimit(). Fixed cross-section in compounds.
|
|
|
|
o Hadronic Processes:
|
|
------------------
|
|
+ models/CHIPS:
|
|
o G4QCaptureAtRest: added check on 4-momentum balance for violations
|
|
of more than 2 GeV; repeat sampling again. Check baryon number of
|
|
final state and take into account nuclear recoil at rest which is
|
|
not produced as a final particle.
|
|
|
|
o Track:
|
|
-----
|
|
+ Fix to reset 'RestMass' in G4FieldTrackUpdator::Update() method
|
|
as it is used to initialise each track by ParallelWorldScoringProcess.
