Question G4UserLimit for gammas 

Forum: Physics List
Date: 17 Feb, 2011
From: Thomas Melzig <Thomas Melzig>


as far as I understand the SetUserMinEkine()-method in G4UserLimits works only for charged particles. I want gammas to be affected by the same limit, so that they are not generated if their energy is below the threshold.

I thought the following code in the PhysicsList should do that:

  G4UserSpecialCuts* userCuts = new G4UserSpecialCuts();
    G4ParticleDefinition* particle = theParticleIterator->value();
    G4ProcessManager* pmanager = particle->GetProcessManager();
    G4String particleName = particle->GetParticleName();
    if(particleName=="e-" ||
       particleName=="e+" ||
      pmanager ->AddDiscreteProcess(userCuts);

But that doesn't work as I can see in the tracking output. Is there a simple method to prevent gammas from a certain energy on to be tracked?

Thanks in advance
