Kostalos, J

Tests were conducted to determine the performance of a fission counter detector and the associated pulse amplifier chain when the counter is subjected to an intense gamma flux. The fission counter filling gas was 99% angon + 1% nitrogen at 1 atm. pressure instead of the original filling of 2 atm. of nitrogen. The results of the tests indicate that a 50% reduction in over-all gain and a minor change in the preamp input circuit were necessary, and in the presence of about 10/sup 5/ r/hr gamma flux, the sensitivity of the system is reduced by 20%. This sensitivity is defined as the number of neutron counts for a given flux with the background counting rate set at 10 cps. (auth)
