Dear Geant4 experts,
I am simulating 12C ions passing through 70mm of AIR and after that hitting 20mm of PMMA (drawing attached) The macro is this one:
/gps/ion 6 12 6
/gps/energy 1140 MeV
/run/SetCut 0.1 um . .
The physics list I am using is this one:
" "(new G4EmExtraPhysics());
" "(new G4RadioactiveDecayPhysics());
" "(new G4HadronElasticPhysicsHP());
" "(new G4EmHadronPhysicsQGSP_BIC_HP());
" "(new G4StoppingPhysics());
" "(new G4IonElasticPhysics());
" "(new G4IonPhysics());
And the setCuts:
I've defined the PMMA's volume as sensitive and then I calculate the energy deposit by all the particles, only by primaries and only by secondaries in the PMMA. The histogram I get is attached. Can anyone help me to understand the thin second peak that apear in the right region of the principal peak? I do not understand why I observe it in all the histograms.
