Question Fluorescence with Livermore or Penelope lists on GRAS 

Forum: Physics List
Date: 03 Dec, 2015
From: Leonardo Ghizoni <Leonardo Ghizoni>

Hello,

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:

G4int ncomponents,natoms;

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);

YAG->AddElement(Y,natoms=3);

YAG->AddElement(Al,natoms=5);

YAG->AddElement(O,natoms=12);

I cannot produce the fluorescence. Is there another process I have to initialize? Or definition on the material?

Thank you. Leonardo.
