Hi,

Everything seems OK in your input, just a few comments:
If you want to get results normalized by area, you should input the area of your target cylinder in WHAT(6).
You set maximum neutron kinetic energy as 100 MeV, minimum neutron kinetic energy to 0.0 and the number of bins between the two as 10. Bear in mind that FLUKA uses a multi-group (260 groups) approach for low energy neutrons below 19.6 MeV and that the minimum energy in that approach is 1E-14GeV, not 0.0. So the resulting histogram is going to have that binning structure regardless of what you request.

    Dear FLUKA Experts,
                        I want to calculate the emitted neutron flux (per cm
    square per GeV per primary) when a proton beam of 100 MeV interacts with
    the Tungsten target of length 1.2 cm and diameter 5.0 cm. The proton
    beam diameter is 4.0 cm. I am using USRBDX card. The input is attached
    herewith. Please help.
