Hi all,
I am trying to model the scatter produced from a low energy photon beam (20 keV - 30 keV) interacting with a perspex block and being detected by a thin layer of CdTe as my detector.
A few questions I have are firstly I have chosen EM-CASCA but found I was getting very little scatter in my spectrum so tried PRECISION but I only got errors, is there a reason why PRECISION wouldn't work?
Secondly I played around with the EMFCUT and DELTARAY options but this had no effect. Does anyone have any suggestions as to why you think I am getting such a small amount of scatter on my spectrum?
Here are the beam characteristics I used:
* 20keV photon beam
* Momentum spread (?p) = flat - 0GeV/c
* Divergence type (??) = Gauss - 100.00mrad
* Beam shape (x-axis) = Gauss - FWHM 0.05cm
* Beam shape (y-axis) = Gauss - FWHM 0.05cm
The initial beam position was at -10cm on the z axis and the number of start events was 1E7.
Thank you for any suggestions you may have
Faith
