The Electronic group of Subatech is designing, testing and commissioning  readout systems for the research teams of SUBATECH. 

Our main tasks are, locals and regionals boards for ALICE-MID, Flex design,  and Power Supply Unit for ALICE-MFT, the readout chain, data acquisition and command/control for XEMIS2, readout ASICS, and signal processing for CODALEMA-EXTASIS along with general electronic support for radiochemical group and education.


We take part to "Electronics engineer network of IN2P3", "Electronics engineer national network of CNRS and EPST" and "Software designer network of CNRS"
