放射性裂变产物85 Kr的大气浓度高于基线被认为是秘密分离钚的最佳指标。此外，它的高挥发性使其适用于检测核废料容器和受损燃料包壳的泄漏。目前正在开发用于超痕量分析的分光计，并将优化用于85 Kr的大气监测。该设备基于共线共振电离光谱的改进形式，这是ISOLDE-CERN开发的一种用于对奇异核进行精确测量的技术。该设备的动机进行了探讨，沿着进展和未来的发展的概述。
A higher than baseline atmospheric concentration of the radioactive fission product 85 Kr is considered to be the best indicator of clandestine plutonium separation. Additionally, its high volatility makes it suitable for detecting leaks in nuclear waste containers and damaged fuel cladding. A spectrometer for ultra-trace analysis is currently under development and will be optimised for atmospheric monitoring of 85 Kr. This device is based on an adapted form of collinear resonance ionisation spectroscopy, a technique developed at ISOLDE-CERN for performing precision measurements on exotic nuclei. The motivation for this device is explored, along with an overview of progress and future developments.
