Abstract

Neutron induced prompt gamma-ray spectroscopy (NIPS) system equipped with a <TEX>$^{252}Cf$</TEX> neutron source and a n-type coaxial HPGe detector was installed for the quantitative analysis of aqueous samples in KAERI, Korea. Since the thermal neutron flux for the <TEX>$^{252}Cf$</TEX> neutron source is relatively low compared to that for the reactor, the use of a thermal neutron reflector in the NIPS system may lead to improved results. The enhancement by using various reflectors was carried out by comparing the Cl peak with or without a cadmium plate between sample and the <TEX>$^{252}Cf$</TEX> source. The use of pyrolitic graphite as a reflector provided a good result.
