Question Tracking Ions 

Forum: Particles
Date: 28 Nov, 2003
From: Christian Bongardo <Christian Bongardo>

I have problems with tracking ions (Li, C, N, O and Fe). It seems as if the ion passes through matter without leving signs on it. Here my particle def.:

G4ParticleDefinition* ion
    = particleTable->GetIon(pNatomic,pMatomic,0.);
(in which I put the right value of pNatomic and pMatomic)

here my ion physics (taken from Mulassis):

pManager = G4GenericIon::GenericIon()->GetProcessManager();
  // add process

  if (mode == "Ion") {
    G4hIonisation* fIonIonisation = new G4hIonisation();
    pManager->AddProcess(fIonIonisation, ordInActive,2, 2);

  } else {
    G4hLowEnergyIonisation* fIonIonisation = new G4hLowEnergyIonisation();
    pManager->AddProcess(fIonIonisation, ordInActive,2, 2);

  pManager->SetProcessOrdering(&fIonMultipleScattering, idxAlongStep,  1);
  pManager->SetProcessOrdering(&fIonMultipleScattering, idxPostStep,  1);

Perhaps the solution is obvious, but not to me...

Thanks, Chris
