Re: Fluence Versus Time

Dear Dr. Sala,

Thank you for your help. It worked very well for the neutrons. I have
another request which I can't solve it. If I use the same fluscw.f routine
for the secondary particles like protons. Fluka will take into account the
protons versus time (starting from the proton production). What should I
do if want to score the protons extracting the water sphere versus total
time (Starting from the primary particle like neutron and continuing with
secondary particle like proton). It could be achievable if I could add the
ATRACK of proton with neutron in fluscw.f user routine. I would like to
also thank Dr. Fasso for his wise remark, which worked very well.

Best Regards,
Reza Taleei.
