Hi, I want to simulate primary ionization distance and the number of secondary electron produced by primary ionization per unit length when a charged particle passes through TPC gas. For TPC gas mixture 70% Ar+30%Isobutant, at normal condition the average distance between primary ionizations for fast particle should be around 300 um.
But my simulation result is about 1 mm for 500MeV electron when I set " G4ProductionCutsTable::GetProductionCutsTable()->SetEnergyRange(10*eV, 1*GeV)" in PhysicsList and "/testem/phys/addPhysics livermore".
Now I suspect whether Geant4 could simulate the number of secondary electron in the TPC gas
Looking forward to reply!
