摘要:
Purpose: Liquid scintillator is the target material of neutrino in Jiangmen Underground Neutrino Observatory (JUNO) detector. it is necessary to control the radon at a very low level. Methods: In this work, a device was set up to strip the radon from liquid scintillator with high-purity nitrogen bubbling, and the radon carrier nitrogen was collected into radon measurement chamber to measure radon concentration, then the stripping efficiency of radon in liquid scintillator can be measured. Results: Under normal temperature and 2 L/min gas flow r...
