Dear FLUKA Experts,
I simulated a spherical beta source having a spectra ( max beta energy 0.15
MeV) and tried to obtain electron spectra as well as Bremsstrahlung spectra
at a detector position. To do this I have used two USRBDX card, one with
WHAT(2) particle: ELECTRON and other one with WHAT(2) particle: PHOTON. I
have used 1E-05 GeV as electron cut-off and 1E-6 GeV as gamma cut-off in
both transport and production cut-off card. The output file contains > 10%
error in the USRBX result for both electron and photons although the
particle histories are 5E+9.
I have following queries:
1. Is this the correct way of estimation of Bremsstrahlung spectra?
2. The Emax and Emin values in the USRBDX card for electron have been
taken from the min and max energy in the beta spectra which I have used as
input in the source file. What are the values of Emax and Emin for scoring
photons (Bremsstrahlung spectra)?
Thanks and Regards
