Dear FLUKA experts,
I have a simple setup of a 200 MeV proton beam incident on a 1mm slab of
water. I am scoring energy deposition with SCORE.
The stopping power for a 200 MeV proton is 4.491 MeV/cm or 449 KeV in a 1mm
slab.
However, SCORE shows about 463 KeV of energy deposition, 14 KeV more than
expected. This is to much energy to be from nuclear stopping power.
Am I missing some physics here? Surely the energy deposition should be
almost entirely due to inelastic coulomb scattering and should just be
dE=(dE/dz)dz where dE/dz is the stopping power.
Thanks very much,
