I'm working with GRAS as an external application for a fluorescence monitor.
An incident electron beam hits a YAG (Ytrium Aluminium Garnet) screen to produce fluorescence. I'm unable to produce the fluorescence till now.
I called the physics list in the following ways: G4UImanager* UImanager = G4UImanager::GetUIpointer();
UImanager->ApplyCommand("/gras/physics/addPhysics em_livermore"); or UImanager->ApplyCommand("/gras/physics/addPhysics em_penelope");
Based on other questions in the forum and on the developer's guide(for the production of fluorescence), I set cut and lowest energy as:
UImanager->ApplyCommand("/run/setCut 0.1 um");
UImanager->ApplyCommand("/cuts/setLowEdge 250 eV");
The YAG screen is defined as follows:
G4double density_YAG = 4.56*g/cm3;
G4Element* Y = nist->FindOrBuildElement("Y");
G4Element* Al = nist->FindOrBuildElement("Al");
G4Element* O = nist->FindOrBuildElement("O");
G4Material* YAG = new G4Material("YAG",density_YAG,ncomponents=3);
I cannot produce the fluorescence. Is there another process I have to initialize? Or definition on the material?
Thank you. Leonardo.
