| Research Abstract |
A new low-energy neutron spectrometer for accelerator based neutron source (ABNS) for BNCT has been developed. For BNCT, it is a crucial issue to characterize the neutron field especially for ABNS. However, measurement of epi-thermal neutrons is not straightforward. In this study, using a position sensitive proportional counter as its one edge of the two is an entrance window of neutrons, detection depth distribution is measured. The measured detection depth distribution is converted to the neutron energy spectrum. Prototype detectors were produced to confirm the feasibility to measure the neutron spectrum in energies from thermal to epi-thermal region.
