I think I have the same problem described in the following post, could someone please confirm my suspicion:
Weird Gamma Spectrum in P+C reaction
If so, is there any future plan to make Fluka more “PGNAA friendly”?
I’m trying to demonstrate prompt gamma neutron activation analysis by directing
a beam of thermal neutrons at a silicon target (source files attached). The idea is
to view the prompt gamma peaks by plotting the energy spectrum of the gammas entering a target area. However, instead of getting nice sharp peaks where expected (e.g. 3539.0, 4934.0, 6379.8 and 7199.2 keV etc), I get rectangular columns all having widths of precisely 500 keV:
Any help fixing this problem would be most welcome,
