摘要：

The radioactive decay of radon (Rn-222) and its progenies are significant background sources in an extremely low background environment, interfering with investigation like detecting dark matter and observing neutrinos. In this paper, a 1000 L ultra-high sensitivity radon monitor for China Jinping Underground Laboratory (CJPL) based on electrostatic collection and Au-Si surface barrier detector was developed. The monitor is capable of distinguishing Rn-220 from the energy spectrum and effectively eliminating any interference caused by Rn-220. A...
