Hello Sergey, To create secondaries, you have to tell first to fastStep how many of them you create: fastStep.SetNumberOfSecondaryTracks(G4int); and then invoke the helper method CreateSecondaryTrack(...) for each of them calling either: fastStep.CreateSecondaryTrack(dynamicParticle, // const G4DynamicParticle& polarization, // G4ThreeVector position, // G4ThreeVector time, // G4double, localCoordinates // G4bool, with a default value "true"); or fastStep.CreateSecondaryTrack(dynamicParticle, // const G4DynamicParticle& position, // G4ThreeVector time, // G4double, localCoordinates // G4bool, with a default value "true"); these two methods return a G4Track pointer on the track created. You may alternatively create a G4Track by yourself and pass it to fastStep: G4Track* secondary = new G4Track(...); fastStep.AddSecondary(secondary); You can look at the G4FastStep.hh header file in source/processes/parameterisation/include for more details. Please let me know if this helps.
