| Abstract;Since 1991, the JRR-3M prompt gamma-ray analysis system has been utilized by the scientists both from foreign countries and Japan. Recently new BGO detectors and charged particle spectrometer were installed to the PGA system to improve ability of the system. Background count rate of Bi-207 decreased by factor ten and only double escape peaks detected in the pair mode spectrum by the improvement. Furthermore, neutron depth profiling of boron and lithium has become possible by the improvement. (author abst.) |
