Dear FLUKA users,
=20
I am a relatively new user of FLUKA and am attempting to reproduce the
results obtained in a paper. The authors used EGS4 to model doses in an
ICRU4 detector, from a 6GeV electron beam which strikes a copper
absorber, behind which the detector is located. The paper is
'Calculation of electron-photon doses behind beam absorbers at high
energy electron accelerators' by Dinter, Pang and Tesch, published in
Rad. Prot. Dosim. Vol 28 No.3 (1989).
The authors calculate both dose and a quantity referred to as 'photon
kerma' in the report. Whilst I have been able to obtain good results for
dose using FLUKA's SCORE command with generalised particle type 211
(e+,e- and photons), I am not sure how I would calculate the photon
kerma (in terms of what estimators to use, how to identify only the
particles from primary interactions, etc). Can anyone suggest how this
might be done?

Many thanks,
