In Search of Higher Sensitivity Pu Isotopic Analysis
Hiromu Kurosaki, D Chang, Kenneth G. Inn
Thermal ionization mass spectrometry (TIMS) is an effective method for isotopic and ultra-sensitivity determination of plutonium. This project aims at improving the NIST TIMS sensitivity for the analysis of plutonium from environmental sample. The TIMS detection limits for direct, electroplating, and resin bead source loading techniques were determined by systematically varying the amount of plutonium source loaded on the rhenium filament. It was shown in preliminary works that the resin bead could product a stable TIMS ion beam for as long as 6 hours for the measurement
