Dear FLUKA Experts,

I'm simulating the SR in a chamber. To test the photon generator, I built a geometry with a chamber(RCC with 5.0cm in a, 3.75 cm in b, and 880 cm length) and a pipe(RCC cylinder shell with 5.3 cm in a, 4.05 cm in b, and 880 cm in length), both with the material of vacuum. Then I used two USRTRACK cards to record the volume fluence of chamber region and pipe region, and a USRBDX card to record the one-way fluence from chamber to pipe(I set the real number of volume and area). In my opinion, I should get the same number of these three records, but I did not. So I'd like to know the reason for these, especially why two USRTRACK cards give the different results. And also, if I want to get the real number of photons or whatever particles from the results, from particles per cm^2 to particles, how do I process the results?

Thanks a lot!
