Question How to Distinguish Fluorescence Photon from Bremsstrahlung Photon? Check the Process Creat the Track?

Hi there,

I really need your expertise.

I am doing simulation with electron of 55~80keV hitting Gd target. Both bremsstrahlung photon and fluorescence photon are created, but I am interested in counting only the photons created by fluorescence. My questions are:

1. How can I count only the fluorescence photon? I am thinking about using check the process creat the track. Is this reasonable?

2. In order to get fluorescence photons. Should I just use G4LowEnergyIonisation? Can I use G4PenelopeIonisation to get these photons?

3. In order to trace the process creating the track of fluorescence photon, what is the right code to do that? I did some research on this part but still didn't get clue what should I write.

Could anybody familiar with this kind of simulation please give me several lines of code that I can make use of, or tell me which example program has similar function which I can refer to, of tracing the process that creats fluorescence photon or any other particles.

Any suggestion and help of any kind are highly appreciated.

Sincerely,

Colin
