Cryogenic detectors for dark matter: from scinitillation to brittle fracture

低温量热仪正朝着理解构成我们宇宙中大部分物质的暗物质的性质迈进。 这些探测器在略高于绝对零度的温度下工作，就像记录粒子相互作用的非常灵敏的温度计。 再加上电离或闪烁的测量，他们能够拒绝占主导地位的放射性背景。 虽然电离量热计目前在灵敏度上具有优势，但需要更多的目标来了解剩余的背景并验证暗物质信号，以及进行其他稀有事件搜索。 因此，我们建议在低温下研究各种材料的闪烁，以制作闪烁量热计。

Cryogenic calorimeters are striding towards understanding the nature of the dark matter that constitutes most the matter in our Universe. Operating at a temperature barely above absolute zero, these detectors act as very sensitive thermometers registering particle interactions. Coupled with a measurement of ionization or scintillation, they are able to reject the dominant radioactive backgrounds. Though ionization calorimeters currently have an edge in sensitivity, more targets are needed to understand the remaining backgrounds and verify a dark matter signal, as well as to carry out other rare-event searches. We therefore propose to study the scintillation of various materials at low temperature to make scintillation calorimeters.
