Dear Peter and other masters,
I have a question concerning the photocathode simulation. Here my codes are give below:
........ G4MaterialPropertiesTable* PMT_SD = new G4MaterialPropertiesTable(); PMT_SD->AddProperty("REALRINDEX", PhotonEnergy_Bialkali, realRefractiveIndex_Bialkali, nEntries_Bialkali); PMT_SD->AddProperty("IMAGINARYRINDEX", PhotonEnergy_Bialkali, imaginaryRefractiveIndex_Bialkali, nEntries_Bialkali); PMT_SD->AddProperty("EFFICIENCY", PhotonEnergy_Bialkali, quantumEfficiency_Bialkali, nEntries_Bialkali);
// define the optical surface for the bialkali photocathode of PMT G4OpticalSurface* bialkaliSurface = new G4OpticalSurface("bialkaliSurface"); bialkaliSurface->SetType(dielectric_metal); bialkaliSurface->SetFinish(polished); bialkaliSurface->SetModel(glisur); bialkaliSurface->SetMaterialPropertiesTable(PMT_SD);
For the readout part, I following the instruction of this: http://hypernews.slac.stanford.edu:5090/HyperNews/geant4/get/opticalphotons/11/1.html and the example code: http://www-geant4.kek.jp/lxr/source/examples/extended/optical/LXe/src/LXeSteppingAction.cc
But I can not get the "Detection" results, when I call the G4OpBoundaryProcess::GetStatus() function.
I go further to check the source code of G4OpBoundaryProcess class, I can not find any code to give the "Detection" value to the status variable.
So, now I feel confuse about the function about Detection simulation.
In addition, when I changed the Efficiency vector, the program doesn't show any change.
Could you please help me to figure out my problem?
