Question strange proton energy loss 

Forum: Geometry
Date: 07 Jul, 2010
From: Simone <Simone>

hello to everyone,

in my simulation MIP protons (2 GeV) impact on a thin layer made of bismuth. the energy deposited anyway seems not to scale linearly with the layer thickness (wich is strange since dE<<E): with 1 cm thickness I get a total energy deposition with a peak around 10 MeV, while with 1 micron i get a energy deposition of ~0.3 keV (while I expected 10MeV/10000=~1keV).

it is surely not due to secondaries escaping the 1 micron layer, since i used an extremely high cut value to avoid that effect

does someone has any suggestion/ideas about this strange behaviour?

thanks
