标题： MIMAC : A micro-tpc matrix for directional detection of dark matter

摘要： 定向探测非重子暗物质是一种有前途的搜索策略，可用于区分WIMP事件和背景。 然而，这种策略需要对能量进行精确测量，低至几keV，并对轨迹进行三维重建，低至几毫米。 为了达到这个目标，开发了MIMAC项目。 它基于一个充满3He、CF4和/或C4H10的气体微-TPC矩阵。 展示了利用低单能中子场获得的低能核反冲（1H和19F）的初步结果。 讨论并通过MIMAC可访问的一个现实案例说明了这种搜索策略的发现潜力。 显示英文摘要

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.
