天体物理观测已经为暗物质的存在提供了令人信服的证据,然而对暗物质粒子的直接观测还没有最终建立起来。DAMA实验声称利用意大利格兰萨索实验室的NaI探测器观测到了暗物质的年度调制信号。DM-Ice项目的目标是在南极用一个新的探测器阵列最终验证这一说法。这将是南半球首批直接探测暗物质的实验之一。DM-Ice17是部署在南极冰面上的17公斤NaI探测器的原型。演讲者将报告探测器收集到的第一手数据,并讨论全尺寸DM-Ice探测器的研发进展和前景。
Astrophysical observations have provided convincing evidence for the existence of dark matter, yet direct observation of the dark matter particles has not been conclusively established. DAMA experiment claimed to have observed the annual modulation signal of dark matter using NaI detectors at the Gran Sasso Lab in Italy. The DM-Ice project aims to conclusively test this claim with a new detector array at the South Pole. It will be one of the first direct dark matter detection experiments in the southern hemisphere. DM-Ice17 is a prototype 17 kg NaI detector deployed in the South Pole ice. The speaker will report first data collected with the detector and discuss R&D progress and prospects of the full scale DM-Ice detector.
