Dear FLUKA experts,
I have modelled HPGe geometry (by optimizing various detector geometry parameters) in FLUKA and used Gaussian broadening parameters obtained from experiment. While comparing the peak region, I found the FLUKA output is not very smooth. Please note, if we take total counts under the peak and estimate full energy peak efficiency, I am getting similar values as that of experiment. I am wondering if there is any way to improve the smoothness of broadening ? Also, I have noticed the smoothness is more for a Cs 137 source as compared to a Co 60 source (see the attached two figures). I have used a history of 1.25E+7 for 5 cycles in both the cases.
Regards,
Riya
