I am a beginners of Geant4, and now I am simulating a optical process of plastical scintillation . The volume I used is ( from outer to inner ) PAPER , air _empty , , Scintillation, groove, WLS. Some properties I set are : (1) The REF of paper is 0.985 , ; (2) Scintillation: myMPT1->AddConstProperty("SCINTILLATIONYIELD",8000./MeV); myMPT1->AddConstProperty("RESOLUTIONSCALE",1.0); myMPT1->AddConstProperty("FASTTIMECONSTANT", 2.*ns); myMPT1->AddConstProperty("YIELDRATIO",1.0); The number of Photon.Eletrons which was collected by PMT is about 60, buut the time I used is about 1 minute per event. The reason maybe come from the reflection of phontons in the scintillation. So how can I improve my programe to decrease the time used per event? Can anyone give me advice for the this problem? Thanks in advance .
