摘要:

WIMP是一个动机良好的星系暗物质候选者。液态氩(LAr)是直接探测WIMP的理想靶。为了研究激光喇曼探测器的技术和性能,设计了激光喇曼探测器原型。原型探测器的有效体积包含0.65千克液态氩。液氮(LN)冷却系统允许液氩的温度保持在沸点(87.8 K),波动小于0.1 K。原型用Na $^{22}$源校准,光输出1.591 $\pm$ 0.019 p.e./采用国产氩气净化系统,对511 keV γ射线进行了氩离子的净化。

英文摘要:

WIMPs are a well-motivated galactic dark matter candidate. Liquid argon (LAr) is an attractive target for the direct detection of WIMPs. The LAr prototype detector is designed to study the technology and property of LAr detector. The prototype detector have an active volume containing 0.65 kg of liquid argon. The liquid nitrogen(LN) cooling system allows the temperature of liquid argon to be maintained at the boiling point (87.8 K) with fluctuations less than 0.1 K. The prototype was calibrated with a Na$^{22}$ source, with the light yield 1.591$\pm$0.019 p.e./keV for the 511 keV gamma rays using the domestic-made argon purification system.
