title: Measurement and simulation of neutron beam fluence energy distributions at the neutron time-of-flight facility of iThemba Labs.
abstract: A NE213 proton recoil detector using the time-of-flight technique was used to measure neutron beam fluence energy distributions at the neutron time-of-flight facility of iThemba Labs. A comparison was performed between neutron beam fluence energy distributions calculated by the Monte Carlo code MCNPX and that measured for neutron beams of energies up to ∼64 MeV for the calibration of detectors. The results obtained showed good agreement between the calculated and measured distributions.
