Hi,

I'm changing the example icsd and I also found some issues with carbon ions.

In the PhysicsList.cc we have at the line 101:

genericIonsManager->GetIon("carbon");

I include:

#include "G4DNARuddIonisationExtendedModel.hh"

since it is the only one available for carbon ions (http://geant4-dna.in2p3.fr/styled-3/styled-8/index.html).

And:

} else if ( particleName == "carbon" ) {

            G4DNARuddIonisationExtendedModel* c_modelDNARuddIonisationExtended =
            new G4DNARuddIonisationExtendedModel();

            G4DNAModelInterface* c_ionisationInteraction= 
            new G4DNAModelInterface("c_ionisation_interaction");
            c_ionisationInteraction->RegisterModel(new G4DNAVacuumModel());
            c_ionisationInteraction->RegisterModel(c_modelDNARuddIonisationExtended, particle);

            G4DNAIonisation* c_DNAIonisationProcess = 
            new G4DNAIonisation("c_G4DNAIonisation");
            c_DNAIonisationProcess->SetEmModel(c_ionisationInteraction);
            ph->RegisterProcess(c_DNAIonisationProcess, particle);
        }

When I run the application I have no interactions (for carbon ions). I already tried with several energies.

What's missing?

Kind regards,

Pedro Gomes
