Hi,
I am doing fluka simulations to optimize the thickness of x-ray target (tungsten). I have an electron beam of 9 MeV. I hit it on x-ray target. On the other side I want to have Photon flux and electron leakage. I wanted to score electron after target using USRBDX Card in detector region. But I get no flux(0) at output? What could be the problem?
Am I using the Usrbdx Card the wrong way?
Moreover, If I use usrbin card to score anything (like energy deposited or photon flux) in detector region by using region in type in what 1, then I also get the following error.
However, If i define a mesh then i get the results for usrbin.
I have attached my flair file here.
