The South African radionuclide laboratory (ZAL14) supporting the Comprehensive Test Ban Treaty’s International Monitoring System (IMS) is situated at the South African Nuclear Energy Corporation. The laboratory is equipped with two ultra-low background HPGe detectors gamma-spectrometry systems (Canberra BEGe5030 and BEGe65) of which the BEGE5030 has been certified for analysis of IMS samples. To ensure sustainable analytical service for IMS operations, the ZAL14 laboratory aims to commission the BEGe6530 detector as a backup for the current certified detector. The purpose of this study is to verify that the detector complies to the technical requirements for certification listed in table1 of CTBT/PTS/INF.96/Rev.9. Additionally, the performance of the detector will be evaluated by analysis of IMS proficiency test samples and comparing results against the certified detector.
This work is aimed at improving on nuclear test verification methods for testing IMS samples.
