Directional detection of non-baryonic Dark Matter requires 3D reconstruction
of low energy nuclear recoils tracks. A gaseous micro-TPC matrix, filled with
either 3He, CF4 or C4H10 has been developed within the MIMAC project. A
dedicated acquisition electronics and a real time track reconstruction software
have been developed to monitor a 512 channel prototype. This autotriggered
electronic uses embedded processing to reduce the data transfer to its useful
part only, i.e. decoded coordinates of hit tracks and corresponding energy
measurements. An acquisition software with on-line monitoring and 3D track
reconstruction is also presented.
