Outline of Final Research Achievements

Spectral measurement techniques for low-energy components of quasi-monoenergetic high-energy neutron field were developed. Spectral information of the high-energy neutron field above about 100 keV was derived, for the first time, by the time-of-flight method using two types of scintillation detector. Unfolding method for whole-energy neutron spectrometry was performed using gold-activation Bonner sphere spectrometer which is developed to deal with some difficulties of using ordinary proportional counters in the high-energy neutron field. In addition, benchmark experiments of response calibration of neutron detectors were performed to investigate the suitability of calibration method and its dependence on characteristics of detectors and facilities.
