Re: [fluka-discuss]: numerically counting electrons

Dear Elif,
     many thanks for you inquiry to the FLUKA forum.

In FLUKA there are different methods to count secondary particles and
perhaps the simplest way in your case is to use a USRBDX score
with a linear one-way current from the region of your target to the
region surrounding it:

USRBDX 1. ELECTRON -21. TARGET VOID ecount1
USRBDX 1E-3 1E-6 1. &

You can integrate on the energy bins to get the total number,
as in this example, or you can specify more bins to see the
electrons energy distribution.

Please bear in mind that the result depends on the thresholds that
you have set in your problem (electron transport cutoff to be set
with EMFCUT) and also that the result is always normalized per primary
particle, in your case per incident photon.

Also looking in the output file, as suggested by Joachim, is always
very useful. However, being yours a purely electro-magnetic problem, the
table he indicated is not produced since it refers to the products of
nuclear interactions only.

Kind regards,
Andrea
