暗物质定向探测开辟了宇宙学的新领域，使构建核反冲图成为可能，该图将能够探索银河暗物质晕，从而获得此类物质的粒子特征和晕的形状。 MIMAC（MIcro-tpc MAtrix of Chambers）合作在过去几年中开发了一种原始原型探测器，该探测器基于大型像素化微米级与专用快速自触发电子设备的直接耦合，显示了新一代定向探测器的可行性。讨论并说明了这种搜索策略的发现潜力。 2012 年 6 月，第一个双室原型已安装在 Modane 地下实验室 (LSM)，并展示了第一个地下背景事件、增益稳定性和校准。
The dark matter directional detection opens a new field in cosmology bringing the possibility to build a map of nuclear recoils that would be able to explore the galactic dark matter halo giving access to a particle characterization of such matter and the shape of the halo. The MIMAC (MIcro-tpc MAtrix of Chambers) collaboration has developed in the last years an original prototype detector based on the direct coupling of large pixelized micromegas with a devoted fast self-triggered electronics showing the feasibility of a new generation of directional detectors. The discovery potential of this search strategy is discussed and illustrated. In June 2012, the first bi-chamber prototype has been installed at Modane Underground Laboratory (LSM) and the first underground background events, the gain stability and calibration are shown.
