EDELWEISS-2暗物质搜索的现状

Status of the EDELWEISS-2 Dark Matter Search

A. Chantelauze

摘要:

雪绒花计划致力于直接搜索暗物质作为大质量弱相互作用粒子(WIMPs),使用锗低温探测器在法国阿尔卑斯山的莫达内南部地区4800兆瓦的深度进行探测。在总质量为1公斤的第一阶段“雪绒花一号”之后,该方案的第二阶段“雪绒花二号”目前运行着9公斤的探测器和100平方米μ介子否决探测器的主动屏蔽,目前正处于调试阶段。将给出雪绒花II装置的背景现状和性能,并介绍用μ子否决系统测量的地下μ子通量。

英文摘要:

The Edelweiss programme is dedicated to the direct search for Dark Matter as massive weakly interacting particles (WIMPs) with Germanium cryogenic detectors operated in the Laboratoire Souterrain de Modane in the French Alps at a depth of 4800 mwe. After the initial phase Edelweiss I, which involved a total mass of 1 kg, the second step of the programme, Edelweiss II, currently operates 9 kg of detectors and an active shielding of 100 m^2 muon veto detectors and is now in its commissioning phase. The current status and performance of the Edelweiss II set-up in terms of backgrounds will be given, the underground muon flux measured with the muon veto system will be presented.
