Dear Christian,

since you are new to FLUKA I suggest you have a look in the lessons of the FLUKA courses. Specific to your question the following slides will be quite useful to better undestand what you should do.

You can get the information you are after by using the MGDRAW routine. MGDRAW has an entry (USDRAW) which is called whenever you have an interaction (if you activated with the USERDUMP card). In particular, you can distinguish the type of interaction (via the value of ICODE) along with the current region/position in the geometry (via MREG, XSCO, YSCO, ZSCO) and you could access information about secondaries produced in this interaction (looping over particles in GENSTK).

Kind regards

Dear FLUKA experts,

I have s small question about FLUKA. I have a simple geometry in my input file consisting of a CO-60 source and some water phantoms infront of the source.
I want to simulate Photon interactions with my source and the phantoms (material will be changed later).
My question is: How can I score/find out/track or whatever which interactions took place in the run?
Is there a possibility to see how many times photo effects, pair productions, compton effects etc. happened during the run?

I am an absolute beginner with FLUKA. But I can't find an answer to this.

Thanks a lot for your help!
