LOW ENERGY NEUTRONS

Dear Fluka Users
 
I am studying photoneutron processes in targets using FLUKA. In my input file I have an electron beam striking a compound target (Tungsten and gold) and I am scoring neutron fluence in tungsten, gold and lead as shown in the input file.Unfortunately I can not get any neutron output yet iam using a 15MeV beam but photoneutrons are generally produced from 10MeV onwards in most materials.
 
 Can someone please help me to identify what could be wrong with my input file?
 
Thank you
 
Lawrence
