energy flux on EC
- geant3 has EM process total energy cut at 1MeV
- Both SIDIS and PVDIS have confirmed energy flux on EC by the genat3 simulation in the proposals.
- geant4 geometry and materiel checked, no simple mistake found.
- with energy cut on 1MeV, SIDIS geant4 result is close SIDIS geant3, but PVDIS geant4 is still one order larger than PVDIS geant3.
- More careful study like particle type, hit processing under way.
rate on GEM
- rate on GEM need more study, particular from photon-induced rate, SBS has more mature simulation tested with data, their photon-induced rate is about twice of electron rate, need to learn from them.
