Hi all,
My sensitive detector is an array of detectors. I want to add deposited energy of the same detector. For example, if in one event two detectors have deposited energy, then I want to store the two IDs of the detectors and the corresponding deposited energy. My code implemented as following,
void MySensitiveDetector::ProcessHits(G4Step* step, G4TouchableHistory*){
G4int copyNumber = aStep->GetPreStepPoint()->GetTouchableHandle()->GetCopyNumber();
G4double edep= aStep->GetTotalEnergyDeposit();
G4String pname=aStep->GetTrack()->GetDefinition()->GetParticleName();
if (edep > 0.0){
copyNumbers.push_back(copyNumber);
energyStep.push_back(edep);
if (std::find(id_unique.begin(), id_unique.end(), copyNumber) == id_unique.end()){
id_unique.push_back(copyNumber);
}
G4cout<<"ID: "<<copyNumber<<" energy: "<<G4BestUnit(edep,"Energy")<<" particle: "<<pname<<G4endl;
}
}
void MySensitiveDetector::EndOfEvent(G4HCofThisEvent*)
{
G4double deposit=0.0;
for(unsigned int k=0; k< energyStep.size(); k++){
deposit +=energyStep.at(k);
}
if(deposit > 0.0) {
G4AnalysisManager *man=G4AnalysisManager::Instance();
for (const G4int & id: id_unique ){
G4double deposited_energy=0.0;
for(unsigned int i=0; i< copyNumbers.size(); i++){
if(copyNumbers[i]==id)
deposited_energy += energyStep.at(i);
}
if(deposited_energy > 0.0){
man->FillNtupleIColumn(0,0,id);
man->FillNtupleDColumn(0,1,deposited_energy);
G4cout<<"summary: id: "<<id<<" total energy: "<<G4BestUnit(deposited_energy,"Energy")<<G4endl;
man->AddNtupleRow(0);
}
}
}
copyNumbers.clear();
energyStep.clear();
id_unique.clear();
}
It seems that the codes work for most events, but I noticed abnormal pheno in a few events like,
G4WT9 > ID: 1 energy: 3.5354 keV particle: gamma
G4WT7 > ID: 0 energy: 4.3397 keV particle: gamma
G4WT9 > ID: 1 energy: 296.777 eV particle: e-
G4WT7 > ID: 0 energy: 9.6224 keV particle: gamma
G4WT7 > ID: 0 energy: 920.745 eV particle: e-
G4WT7 > ID: 0 energy: 16.9222 keV particle: e-
G4WT7 > ID: 0 energy: 409.465 eV particle: e-
G4WT7 > ID: 0 energy: 17.7855 keV particle: e-
G4WT7 > summary: id: 0 total energy: 50 keV
G4WT7 > -------- event ID: 99669 end---------
In the event above, the detector with id=0 and id=1 both have deposited energy, but when I sum the energy of each detector, it seems only the detector withid=0 have deposited energy. The tested incoming particles are gamma ray with energy 50.0 keV .
The energy deposited in detector with id=0 is 50 keV, in this case the detector withid=1 should not have deposits. The code is excuted in multi-threads mode. Is there any thing needed to modify in my code to make it more reasonable?
