Description
We have studied saturated LiCl water solution for the neutrino detection for Jinping Neutrino Experiment. The solution takes advantage of the high electron-neutrino charge-current interaction cross-section with Li-7, high natural abundance of Li-7, and the high solubility of LiCl. We have achieved a 50-m long attenuation length at 430 nm. The solution is good in studying energy-dependent solar neutrino physics, including the solar neutrino upturn effect and light sterile neutrino. The sensitivity of a hundred-ton-scale Jinping detector is comparable with other multi-thousand-ton detectors. The contained Cl-35 and Li-6 also make a delayed-coincidence detection for electron-antineutrino possible. The Jinping Neutrino Experiment can measure the crust geo neutrinos of Tibet. In addition to being a pure Cherenkov detector medium, a wavelength shifter, carbostyril 124, is added to the LiCl aqueous solution enabling the development of lithium salt fluorescent water.
