DEDICATED FRONT-END AND READOUT ELECTRONICS DEVELOPMENTS FOR REAL TIME 3D DIRECTIONAL DETECTION OF DARK MATTER WITH MIMAC.

A complete dedicated electronics, from front-end to back- end, was developed to instrument a MIMAC prototype. A front end ASIC able to monitor 64 strips of pixels and to provide their indi- vidual "Time Over Threshold" information has been designed. An associated acquisition electronics and a real time track reconstruction software have been developed to monitor a 512 channel prototype. This auto-triggered 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. The electronic designs, ac- quisition software and the results obtained are presented.
