Dear FLUKA user,

it seems your 1mm thick tungsten target shields your scoring region behind
it from the low-energetic photons which are produced. If you put the
following USRBIN-card, you will see that there are a lot of photosn
scattered in the -z-direction:

USRBIN 11. PHOTON -21. 7.5
3.PhoBIN
USRBIN 0. -2. 75. 50. &

Your USRYIELD scoring only scores photons that would make it through the
tungsten foil. So you probably would want to make the foil thinner to see
something behind it (or increase the electron beam energy).

Cheers,

         Stefan
