                      BrillianceNeutron Source (HBS) project is presented. A total
                      of 450 simulations with the Monte Carlo code PHITS were
                      analyzed to exploredifferent combinations and thicknesses of
                      pre-moderator and moderator materials. For each case, the
                      highest epithermal outgoingneutron current at the end of an
                      extraction channel was obtained. Analysis of the outgoing
                      current density showed that the neutronspectra are
                      independent of the proton pulse width, while the integral
                      outgoing current is proportional to the pulse width,
                      indicatinga trade-off between the time resolution obtained
                      and the neutron flux per pulse expected at the sample
                      position. The neutrontime distribution analysis showed that
                      D2O as pre-moderator, combined with D2O, 7LiF or graphite as
                      moderators, will provide acompetitive epithermal neutron
                      current. The averaged epithermal and fast values obtained
                      for the 96 Hz station and 167 μs protonpulse width are
                      9×109 cm−2 s−1 and 2×1010 cm−2 s−1 for the
                      epithermal and fast neutron extraction channels,
                      respectively, withreductions expected for short proton
                      pulses in burst-mode operation.},
