Abstract
Several methods were explored for improving the glow discharge optogal vanic signal that can be used for determining uranium isotope ratios, The discharge was conditioned by purification of the argon feed gas, u se of a non-evaporable zirconium alloy getter, condensation of dischar ge impurities on a cooling loop near -180 degrees C, and inclusion of tantalum metal in the sample cathodes to serve as a source of sputtere d Ta atoms. Signal improvements of up to 20-fold were observed.
