Abstract

The Jiangmen Underground Neutrino Observatory (JUNO) is a 20 ktons liquid scintillator detector with multi-purpose measurements. Due to low background requirement of the experiment, a multi-veto system ,which consists of a water Cherenkov detector and a top tracker detector, for passive shielding and cosmic muon detection is required.In order to keep the water quality good and remove the radon in the water, a ultrapure water system, a radon removal system adn radon concentration measurement system have been designed.In this poster, the detail informaton of them have been presented.

江门地下中微子观测站的供水系统和氡测量系统
江门地下中微子天文台(JUNO)是一个20万吨的液体闪烁体探测器,具有多用途测量。由于实验背景要求低,需要一个由水切伦科夫探测器和顶部跟踪探测器组成的多通道系统,用于被动屏蔽和宇宙介子探测。为了保持水质良好,去除水中的氡,设计了超纯水系统、除氡系统和氡浓度测量系统。在这张海报中,详细介绍了他们的信息。
