Description
The measurement of low-levels of radioxenon is an important part of the International Monitoring System (IMS) operated by the Comprehensive Nuclear-Test-Ban Treaty Organization Preparatory Commission (CTBTO PrepCom). These stations are continually measuring the radioxenon in air samples to monitor for nuclear explosions. The IMS also includes laboratories capable of measuring radioxenon archive samples from the stations around the world. One of these noble gas laboratories is operated by the United States, USL16-NGL. In recent years, work has been performed to improve the sample throughput and sensitivity of these laboratory systems. In this presentation, we detail a new system capable of processing multiple samples automatically and measuring four samples at a time. We will also discuss methods being used to improve the flexibility for number of samples and xenon sample volume, while also allowing for replicate measurements for improved accuracy. Additionally, we will show work being done to look at detector resolution improvements capable of improved 131mXe and 133mXe measurement for enhanced radioxenon source discrimination.
