Changes in musrPhysicsList.cc that were needed for new version of
Geant = Geant4.9.4. The changes remove G4MultipleScattering and
MultipleAndCoulombScattering, because multiple scattering has to
be treated differently for different particles in Geant4.9.4 and
"G4MultipleScattering" is not supported anymore. The documentation
has to be updated (i.e. comments about MultipleAndCoulombScattering
has to be removed from doc/musrSim.tex).
1) correction of volume that is assigned to optical photons
(odet_ID) - now it is the volume from postStepPoint instead of
preStepPoint
2) new variable added (nOptPhot) - number of optical photons
generated in the event
This version contains many changes!
1) Optical photon simulation is now possible - some work still may need to be done
(e.g. the manual is not updated yet), but it should basically work already now.
2) Changes in the musrSimAna - correction of some bugs (mainly in the coincidence
of coincidence and veto detectors) and some other improvements
1) The filling of the root tree was called from musrScintSD.cc, which was
problematic, because no variables were written out if there was no
sensitive volume defined (problem for example when one wants to study
the beam-line properties using just save volumes).
Therefore the tree filling is now called from musrEventAction.cc.
2) A possibility to gently stop the run by creating a file with the
name "RUNNUMBER.stop" in the working directory has been introduced.
("Gently" means that root output file is closed properly.)
Added possibility to use mu- (or other particles) as the primary particles
in the G4ParticleGun (this option can be switched on by
/gun/primaryparticle ).
This is the first version of the muSR simulation code (musrSim)
based on the merged codes of Kamil Sedlak and Toni Shiroka.
It should be a running version of the simulation code, however
it has not been very well tested, therefore it will probably
need some further development.
