Dear all,
I want to calculate the theoretical transmission value (I/I0) of polyethylene for 2.45MeV neutron which range from 0.5cm to 3.0cm
thickness and compared with the experimental one. The counting experiment is He3 proportional counting tube. I am confused that
which one I should choose in the USRBDX card to do the simulation:
1) "fluence" with "beampart";2) "fluence" with "neutron";or 3) "current" with "beampart";4) "current" with "neutron";
I am also confused that what the difference is between the "beampart" and "neutron" in the USRBDX card when neutron is scored, thank
you !
Thanks in advance and any help will be appreciated !
