SuperCDMS

天文观测中对引力效应的不一致提供了大量的线索，表明主导宇宙的是一种尚未确定类型的非发光物质。最近的测量结果集中在一个描述宇宙的宇宙学模型上，在这个宇宙中，超过80%的物质由这种所谓的暗物质组成。低温暗物质搜索(CDMS)合作开发了能够同时读出热信号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。双信号读数可以有效区分极其罕见的暗物质相互作用和由背景辐射(主要是来自周围物质中放射性痕量污染物的环境辐射和宇宙辐射)引发的更常见的事件。

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).
