Please see the attachment. I used the photon flux results (f2 tally) through the surface of the Titanium sample in the 1st setup to model it as a photon-emitting surface with a parallel beam incident on a same Titanium sample in the 2nd setup. The photon flux results (f4 tally) in Titanium...

Thanks for your reply, @Alex A. I already did as you suggested. I obtained the energy bin tallies and used them as a secondary surface source. However, the F4 tally results of photon in the sample from the secondary surface source are significantly different from those obtained using the...

Hi, everyone. I am using MCNP to simulate an incident electron beam hitting a tungsten target and obtaining the bremsstrahlung spectra in natural element samples placed behind the initial setup. I want to use the Subroutine Source option in MCNP to record all the directions, weights, energies...
