Dear FLUKA experts and users,
My name is Adrian and I am beginner in FLUKA. I would like to calculate
some correction factors for my detector - free air ionization chamber.
How can I get:
1. the energy deposited in a volume by electrons (and their progeny)
produced in the first interaction with a primary photon;
2. the energy deposited in a volume by electrons (and their progeny)
produced by scattered photons,
3. the energy deposited in a volume by electrons (and their progeny)
produced by fluorescence photons.
I tried with MULSOPT and switched on/off EMFFLUO option but I can not
get good results.
Thanks for your advance,
Adrian
