Abstract
In order to estimate the accuracy of the NMTC/JAERI-MCNP-4A code system, an analytical study is performed for the distributions of reaction rates of various activation samples on the surface of a cylindrical thick tungsten target bombarded with 0.8 and 1.2 GeV protons. It is found through the comparison between the experiment and calculation that the NMTC/JAERI-MCNP-4A code system can represent the reaction rates of the activation detectors which are sensitive to the sub-10 MeV neutrons with an accuracy of 10 to 15%. As the threshold energy of the activation detector increases, however, the agreement becomes worse. The calculated results are 50 to 75% in the C/E ratios for the activation detectors sensitive to the neutrons with tens of MeV. The disagreement suggests that the NMTC/IAERI estimates too low the production of neutrons with energies of several tens of MeV in the thick target. (authors)
