Description

IMB-CNM has been a main actor in the development of Low Gain Avalanche Detectors since the initial device conception, more than a decade ago.
One of the challenges for LGAD is the deterioration of the gain and timing resolution after radiation damage due to the acceptor removal mechanism.
A well-established solution to increase radiation tolerance is carbon co-doping in the gain layer.
Also, the IMB-CNM’s Radiation Detectors Group has revisited its strategy regarding the technological design.
This contribution aims at summarizing the development and performance of the new LGAD technology with and without carbon co-doping at IMB-CNM.
