Thanks for the reply Vittorio. Yes, I have obtained the stopping power tables as you describe, but I don't think that helps me for a volume where I have a shower of charged particles passing through a volume, each particle having different initial energies and path lengths through the volume.

Shouldn't this calculation be available somewhere since FLUKA can provide DOSEQLET in a volume? If so, how can I get this LET? Could I score both DOSE and DOSEQLET in the same volume, and use these values to get average IRCP60 quality factor, then determine track-averaged LET from the Q(LET) equations?

Dear Brandon,
 the track averaged LET is in principle the stopping power.

You can get the stopping power calculated by FLUKA for each
material using the DELTARAY. (See Manual 7.1.3.7 of the pdf,
or 7.12 of the ASCII + references therein)

Best,
Vittorio

Hello,

I know how to use USRYIELD to get LET across a surface, is there a way to get track averaged LET over a volume (i.e. Delta-E/pathlength) in FLUKA?
