Data acquisition electronics and reconstruction software for directional detection of dark matter with MIMAC

Directional detection of galactic dark matter requires 3D reconstruction of low energy nuclear recoils tracks. A dedicated acquisition electronics with auto triggering feature and a real time track reconstruction software have been developed within the framework of the MIMAC project of detector. This auto-triggered acquisition electronic uses embedded processing to reduce data transfer to its useful part only, i.e. decoded coordinates of hit tracks and corresponding energy measurements. An acquisition software with online monitoring and 3D track reconstruction is also presented.
