Question Energy deposite 

Forum: Hadronic Processes
Date: 17 Feb, 2015
From: sergi <sergi>

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/particle ion

/gps/ion 6 12 6

/gps/energy 1140 MeV

/gps/pos/type Point

/run/SetCut 0.1 um . .

The physics list I am using is this one:

RegisterPhysics(new G4EmStandardPhysics_option4());

" "(new G4EmExtraPhysics());

" "(new G4RadioactiveDecayPhysics());

" "(new G4HadronElasticPhysicsHP());

" "(new G4EmHadronPhysicsQGSP_BIC_HP());

" "(new G4StoppingPhysics());

" "(new G4IonElasticPhysics());

" "(new G4IonPhysics());

And the setCuts:

G4ProductionCutsTable::GetProductionCutsTable()->SetEnergyRange(100.*eV, 100.*Gev)

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.
