Hi Stefan,
thanks for your reply. Actually I found out that NIEL-DEP is the energy coming from atoms' displacements caused by impinging particles, I don't need (only) this kind of energy.
I was wondering if there is a way to know which is the process that causes the energy loss, so that I could exclude all that processes different from ionization step by step. By modifying the mgdraw routine, I printed in the file.log all the variables that can help me to understand what's really happening in my simulation (e.g. ETRACK, DTRACK, ICODE etc.) but I found no variable that says to me which is the physics energy loss process.
Moreover, which is the criterion used by FLUKA to separate the various steps? Just to be clear: in the file.log I can see a lot of steps of the same electron, in every step it loses a certain quantity of energy, but why does Fluka separate this process in so many steps? This suggests to me that in every step a certain process occurs (such as ionization, Bremsstrahlung etc.) but I'm not able to get any information about the kind of process right now. And this is what I need to do!
Hope you can help me.
Cheers
Alessia

Dear Alessia
Yes, your assumptions are correct.
I suggest to use a USRBIN scoring for NIEL-DEP. See also an older post on
