Oral

Radiation damage is a concern for employing LGADs in the precision timing detectors at the HL-LHC and for other LGAD applications in strong radiation fields. The origin of the radiation induced loss of gain is found in a reduction of electric field strength in the highly doped gain layer, caused by an apparent de-activation of the acceptor doping and the formation of other defects impacting on...
