Energyloss in thin silicon detectors
type: item
description: Hi, my bachelor student is studying the radiation damage on our luminosity detector sensors. When looking on the total energy loss per track and event in the distributions... I simply do not understand them. Other distributions I have seen in this forum do not seem to show those strange peaks. Are we cutting the edge with 50µm thick sensors at Geant4 and high particle energies (MIP) ? Please have a look to the pages 2-6. Regards Promme

description: By default, in gconfig/g4Config.C: TG4RunConfiguration* runConfiguration = new TG4RunConfiguration("geomRoot", "QGSP_BERT_EMV", "stepLimiter+specialCuts+specialControls"); if you remove "specialCuts"+specialControls" there should be no cuts at all, and the distribution could look better. Could you please try? I have some supects but I am not pretty sure.

description: Hi, we tried your suggestion. Still we observe structure, specially for proton/anti-proton (see page 4). Simulation takes ages now. The real reason must be another one.

description: Have you seen the pid of the particles producing such structure, to understand which physics is involved? Is it present also in MVD, which should have a similar code and detector type?
