| Abstract | ||
| This research took advantage of the new features of the MCNPX 6.2 algorithm to model the 3He (n,p) nuclear reaction. The neutron source for the simulation is Am-Be, which emits neutrons with an average energy of 5 MeV. The 3He gas was encapsulated by a thick layer of paraffin. The results obtained have shown that predicting the count values is preferable. additionally, the new versions of MCNPX 6.2 allow the generation of reaction products from proton and triton in addition to the estimated pulse height spectrum of a 3He detector with a considerable detector wall effect. Moreover, it allows studying the dynamics of these reactions as a function of the structure of the 3He detector. The wall effects are small in our modeling design, so the size of the simulation detector is sufficient.The design of the 3He detector is intended to facilitate research into the actions of these reactions. | ||
