摘要

The effect of the detector characteristics on the performance of an isotopic neutron source device for measuring thermal neutron absorption cross section (Sigma) has been examined by means of Monte Carlo simulations. Three specific experimental arrangements, alternately with BF3 counters and He-3 counters of the same sizes, have been modelled using the MCNP-4C code. Results of Monte Carlo calculations show that devices with BF3 counters are more sensitive to Sigma, but high-pressure He-3 counters offer faster assays. (C) 2007 Elsevier Ltd. All rights reserved.
