SuperCDMS

对引力效应的天文观测提供了大量线索，表明宇宙中存在着大量尚未识别的不发光物质。最近的测量结果集中在一个宇宙学模型上，该模型描述了一个宇宙，其中超过80%的物质由所谓的暗物质组成。低温暗物质搜索（CDMS）合作开发了同时读出热和电离信号的低温探测器，用于非常灵敏地搜索暗物质粒子与普通物质的相互作用。双信号读出允许在极其罕见的暗物质相互作用和由背景辐射引起的更常见的事件（主要是来自周围物质中的放射性痕量污染的环境辐射和宇宙辐射）之间进行有效的区分。

Inconsistencies in astronomical observations of gravitational effects provide hints for large amounts of an as of yet unidentified type of non-luminous matter dominating the Universe. Recent measurements converge on a cosmological model describing a Universe in which more than 80 % of the matter is made up of this so-called dark matter. The Cryogenic Dark Matter Search (CDMS) collaboration has developed cryogenic detectors with simultaneous readout of thermal and ionization signals for a very sensitive search for interactions of dark matter particles with ordinary matter. The dual-signal readout allows for an efficient discrimination between extremely rare dark matter interactions and much more common events induced by background radiation (mostly environmental radiation from radioactive trace contaminations in the surrounding material and cosmogenic radiation).
