氡气和氡气子体为稀有事件搜索实验提供了重要的背景。活性炭对氡有很强的吸附能力,可用于除氡和富集氡。内部226Ra浓度最终限制了其氡浓缩能力。为了测量Saratech活性炭的本底并研究不同温度下的氡吸附能力,开发了带有高灵敏度氡探测器的氡发射测量系统和吸附性能研究系统。本文将介绍 0.71 mBq/m3 高灵敏度氡气探测器以及 Saratech 活性炭在低温下氡吸附能力的测量细节。
Radon and radon daughters pose significant backgrounds to rare-event searching experiments. Activated carbon, which has very strong adsorption capacity for radon, can be used for radon removal and radon enrichment. The internal 226Ra concentration ultimately limits its radon enrichment ability. In order to measure the intrinsic background and study the radon adsorption capability of Saratech activated carbon at various temperatures, a radon-emanation measurement system with a high-sensitivity radon detector and an adsorption-performance research-system have been developed. In this paper, a 0.71 mBq/m3 high-sensitivity radon detector and measurement details of the radon-adsorption capability of Saratech activated carbon at low temperature will be presented.
