EDELWEISS-II实验

The EDELWEISS-II experiment

S. Scorza

摘要:

EDELWEISS是位于Modane地下实验室低放射性环境中的直接暗物质搜索。该实验使用Ge探测器在非常低的温度,以确定最终罕见的核反冲引起的弹性散射的WIMP从我们的星系晕。实验第二阶段的试运行已于2007年完成,涉及7公斤以上的锗。两种新型的探测器,由于表面污染事件的主动拒绝已经证明了实现本阶段的物理目标所需的性能。

英文摘要:

EDELWEISS is a direct dark matter search situated in the low radioactivity environment of the Modane Underground Laboratory. The experiment uses Ge detectors at very low temperature in order to identify eventual rare nuclear recoils induced by elastic scattering of WIMPs from our Galactic halo. The commissioning of the second phase of the experiment, involving more than 7 kg of Ge, has been completed in 2007. Two new type of detectors with active rejection of events due to surface contamination have demonstrated the performances required to achieve the physics goal of the present phase.
