Production cut in Geant4
I noticed that the standard production cut in Geant4 is 700um (only secondary particles with a larger range are tracked). With such a cut basically the delta rays are not tracked in silicon. I tried some simulations and the cluster size seems to be heavily affected by this, while it is just a minor correction to the energy spectrum. Right now, I am fixing the cut in the module DepositionGeant4
using the UI manager just before the run manager initialization:
ui_g4->ApplyCommand("/run/setCut 0.001 mm");
It would be straightforward to select the production cut in the config and set it in this way, but I don't know if this is the right way to go. Moreover, is this something that should be corrected or am I just overly concerned by the delta rays?
