Hi Angel,
Here are some insights. Hopefully, they are helpful.
1. DETECT will score the energy deposition from all particles, including all the secondaries. Yes, you can filter by particle, by customizing the user routine “comscw.f” (in ./usermvax) and adding the USERWEIG card to your input file.
Within the routine, the condition ISCRNG.eq.8 will apply to DETECT, and then you can JSCRNG.eq.-6 to alphas,
e.g.:
IF (ISCRNG.eq.8) THEN
COMSCW = ZERZER
IF (JSCRNG.eq.-6) COMSCW = ONEONE
END IF
1. I think it is OK, like the movement of charges etc. cannot be accounted for per my knowledge. Of course, make sure your semiconductor is made of Si, not Ge or any compound.
1. It looks OK at a first glance.

Subject: [fluka-discuss]: silicon detector of alpha particles
Dear FLUKA users and experts,
We are trying to simulate the energy deposition of alpha particles in Si
(please see 241Am.inp attached) and obtain the energy spectrum of the
alpha particles. As we don't complete comprehend the results I have
several questions:
1. Does the DETECT card score the energy deposition of all particles
(alphas, gammas, electrons, etc.) in the given region? Can we score just
the alphas?
2. Should we do something to account for the semiconductor nature of the
Si or the way it is defined is fine?
3. Should we add more cards with physical process or threshold energies?
Best regards,
Angel
