Title: | A metastable xenon isotope detector for treaty verification | Authors: | Lopes, J. A. M. Morgado, R. E. Conde, C. A. N. |
Keywords: | Radioxenon; Multiparameter detection system; Treaty verification | Issue Date: | 2003 | Citation: | Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment. 501:2-3 (2003) 623-629 | Abstract: | A system to selectively detect and quantify the xenon metastable isotopes 131mXe, 133mXe, 133Xe, and 135Xe has been designed, fabricated, and tested. The system combines high-resolution electron and gamma-ray spectrometry with coincidence/anti-coincidence timing for signal selectivity and background rejection. By utilizing X-ray-fluorescence gating, backgrounds from other sources are expected to be reduced to the sub-becquerel level. Coincidence and anti-coincidence triggers are formed from the several individual detectors that comprise the system and used to identify K-shell conversion electrons and fluorescence X-rays from a 109Cd test source with good efficiencies and energy resolutions (20 keV for the low-energy electrons, ~1.2 keV for the fluorescence X-rays, respectively). | URI: | https://hdl.handle.net/10316/4482 | DOI: | 10.1016/s0168-9002(03)00621-1 | Rights: | openAccess |
