论文摘要
氯化锂水溶液具有很大的潜力，是新型太阳中微子检测器的检测介质。 Nuclide \ ce {^7 li}为MEV尺度太阳能电子中心尼斯提供了高的电流相互作用通道，可实现太阳中微子光谱的测量。这项工作测量了饱和氯化锂溶液的光学特性和光的产量。用活化的碳和重结晶吸附后，该溶液在Bialkali光电层流的敏感波长范围内几乎没有吸收。评估衰减长度在430 nm处达到50米。除了成为纯Cherenkov检测器介质外，将波长变速杆Carbostyril 124添加到LICL水溶液中。确认了光产率的兼容性和增强，从而能够发展出水性富含锂的检测器。
The lithium chloride aqueous solution has great potential to be the detection medium of a novel solar neutrino detector. The nuclide \ce{^7 Li} provides a charged-current interaction channel with a high cross-section for the MeV-scale solar electron-neutrinos, enabling measurement of the solar neutrino spectrum. This work measures the optical properties and the light yields of a saturated lithium chloride solution. After adsorption with activated carbon and recrystallization, the solution shows little absorption in the sensitive wavelength range of the bialkali photomultipliers. The attenuation length is evaluated to reach 50 meters at 430 nm. In addition to being a pure Cherenkov detector medium, a wavelength shifter, carbostyril 124, is added to the LiCl aqueous solution. The compatibility and the enhancement of the light yield are confirmed, enabling the development of a water-based Cherenkov-enhanced lithium-rich detector.
