Title: Neutron spectrum adjustment using reaction rate data acquired with a liquid dosimetry system

Abstract

A dosimetry technique based on neutron activation of circulating water with dissolved salts is discussed. The neutron source was the FNS accelerator at JAERI, Tokai, Japan. Yttrium chloride hexahydrate (YCl{sub 3{center_dot}}6H{sub 2}O) was the salt (264.9 grams dissolved in 16.094 liters of water). Gamma-ray yields were measured with an intrinsic Ge detector. The following reactions were examined: (1) {sup 16}O(n,p){sup 16}N (E{sub thresh} = 10.245 MeV, t{sub 1/2} = 7.13 sec, E{sub {gamma}} = 6.129 MeV); (2) {sup 37}Cl(n,p){sup 37}S (E{sub thresh} = 4.194 MeV, t{sub 1/2} = 5.05 min, E{sub {gamma}} = 3.104 MeV); (3) {sup 89}Y(n,n{prime}){sup 89m}Y (E{sub thresh} = 0.919 MeV, t{sub 1/2} = 16.06 sec, E{sub {gamma}} = 0.909 MeV). This paper describes use of the generalized least-squares (GLS) method to adjust the neutron spectrum.
