I am trying to simulate the electromagnetic scattering of a Deuteron beam on a thin proton target. I see the expected deuteron scatter peak, however I also expect a second peak of protons that can be scattered which I don’t observe. I have described my target using G4materials shown below;
G4double TrgDensity= 2.78e-9*g/cm3;
G4Material* TrgMat = new G4Material(“Target”, z=1., 1.01*g/mole, TrgDensity);
G4Tubs* Trg = new G4Tubs(“Trg”, 0.mm, 3.5mm, 100.*mm, 0.*deg, 360.deg);
G4LogicalVolume logicTrg = new G4LogicalVolume(Trg, TrgMat, “Target”);
I was wondering whether the target as described this way allows for scattering of target protons or whether I need to describe it another way.
