THE MEASUREMENT OF TRITIUM PRODUCED IN A ~(6)LiD SPHERE IRRADIATED BY NEUTRONS FROM D-D AND ~(252) Cf
Abstract
In a 6LiI sphere irradiated by neutrons from D-D and 252Cf, tritium production rate and tritium production distribution were measured with 6LiI (Eu) scintillation detector. The measurement shows that the tritium production rate is 0. 98+0. 05 with 252Cf neutrons and the average tritium production rate is 0. 96+0. 07 with D-D neutrons. Moreover, the two dimensional measurement particle idenification technique was used. The result shows that the measured value of tritium production rate is in accord with the theoretical calculating one within the experimental error range while in the areas of various radius, the tritium production distributions are different from each other. The experimental results can be used for correcting the group constant of neutron production tritium and checking relevant theoretical calculating method.
