Abstract :
A hybrid method for neutron–ion transport has been developed and applied to modeling coated and perforated neutron semiconductor detectors. The method couples the MCNP transport code developed by Los Alamos National Laboratory and a specialized ion transport code. Output from MCNP is passed to the ion transport code to perform ion energy deposition calculations, and in this manner the two codes are married. The process is controlled by a PERL script. Angle dependent efficiency calculation results for perforated rod detectors are presented, and neutron absorption efficiencies are presented for channel and chevron type perforations to show how problems with rod perforations may be overcome.
