Cryogenic detectors for dark matter: from scinitillation to brittle fracture

深冷量热仪正在向理解暗物质的性质迈进，暗物质构成了我们宇宙中最重要的物质。这些探测器在略高于绝对零度的温度下工作，充当非常灵敏的温度计，记录粒子之间的相互作用。再加上电离或闪烁的测量，它们能够排除主要的放射性本底。尽管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，验证暗物质信号，以及进行其他罕见事件的搜索。因此，我们建议研究各种材料在低温下的闪烁，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.
