Actually the solution to your problem is much simpler. Put your target inside a vacuum box or sphere, and use USBDRX to give you
the electron current through the target boundary. A single angular bin and a single energy bin from zero to beam energy will
be sufficient. The difference between the number of incident electrons and the number of escaping electrons is the number of electrons which remain inside the target.
To be sure, you can also have another USRBDX detector counting the BEAMPART particles escaping.

Hi,
If energy deposition does not suit you, how about net charge (NET-CHRG on USRBIN card region scoring)?
Otherwise, you would have to go through a user routine like mgdraw.f, where you can count particles escaping your target (you can discriminate based on particle type, energy, etc. and also on whether it is a primary or not).
You would print final results through usreou.f

Subject: [fluka-discuss]: Scoring number of primaries in each region
Dear FLUKA users,
I am trying to determine the number of particles which are deposited in materials. I simply want to determine the thickness of a material in order to stop a certain amount of incident electrons. I understand that fluence and current can be scored with USRBDX, but for now I just want to know how many electrons are escaping the system. Is there a way to do this? From what I have found so far, it is possible to score the energy deposited by the beam, but this is not exactly what I'm looking for.
Thanks,
Alex
