I have found that in geant4.7.0.p01 looping particles are not really killed.
I tracked electron of 1 GeV in a uniform magnetic field in Vacuum: density = 1.e-25*g/cm3; pressure = 1.e-19*pascal; temperature = 0.1*kelvin; G4Material* Vacuum = new G4Material(name="Galactic", Z=1.,A=1.01*g/mole, density, kStateGas,temperature,pressure); ...............................
magField = new G4UniformMagField(G4ThreeVector(0.,0.,4.*tesla)); fieldMgr->SetDetectorField(magField); fieldMgr->CreateChordFinder(magField); ................................
The message "G4Transportation is killing track that is looping or stuck This track has 1000 MeV energy." appears AD INFINITUM.
It looks like in G4Transportation.cc fParticleChange.ProposeTrackStatus( fStopAndKill ); does not work.
The same code works properly in geant4.6.2.
What changes in new version? What is the difference between ProposeTrackStatus() method in G4.7.0 and SetTrackStatus() method in G4.6.2 ?
Best regards, Andrey
