摘要:

定向探测非重子暗物质是区分WIMP事件和背景的一种很有前途的搜索策略。然而,这种策略需要精确测量的能量下降到几keV和3D重建的轨道下降到几毫米。为了实现这一目标,MIMAC项目已经开发。它是基于一个气态的微型TPC矩阵,填充有3 He,CF 4和/或C4 H10。本文介绍了用低单能中子场获得的低能核反冲(1H和19 F)的初步结果。这种搜索策略的发现潜力进行了讨论,并说明了一个现实的情况下访问MIMAC。

英文摘要:

Directional detection of non-baryonic Dark Matter is a promising search strategy for discriminating WIMP events from background. However, this strategy requires both a precise measurement of the energy down to a few keV and 3D reconstruction of tracks down to a few mm. To achieve this goal, the MIMAC project has been developed. It is based on a gaseous micro-TPC matrix, filled with 3He, CF4 and/or C4H10. The first results on low energy nuclear recoils (1H and 19F) obtained with a low mono-energetic neutron field are presented. The discovery potential of this search strategy is discussed and illustrated by a realistic case accessible to MIMAC.
