摘要:

本文介绍了一种用于暗物质探测的低温锗探测器的新设计,它利用共面栅事件定位技术提高了背景分辨能力。在Modane地下设施的EDELWEISS II装置中使用原型设备进行的实验表明,这些设备对低能量$β$的排斥效率非常高,接近10 $^5$。这为研究WIMP-核子碰撞截面中超过10 $^{-8}$ pb的范围开辟了道路,正如EURECA项目中提出的一吨低温探测器质量。

英文摘要:

A new design of a cryogenic germanium detector for dark matter search is presented, taking advantage of the coplanar grid technique of event localisation for improved background discrimination. Experiments performed with prototype devices in the EDELWEISS II setup at the Modane underground facility demonstrate the remarkably high efficiency of these devices for the rejection of low-energy $β$, approaching 10$^5$ . This opens the road to investigate the range beyond 10$^{-8}$ pb in the WIMP-nucleon collision cross-sections, as proposed in the EURECA project of a one-ton cryogenic detector mass.
