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
Re: Energyloss in thin silicon detectors
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.
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.
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?
