Description

Since the pioneering proposal of the Low Gain Avalanche Detector (LGAD) concept, IMB-CNM has played along the years a fundamental role in the development of this technology. LGADs have demonstrated an outstanding performance when detecting high-energy charged particles thanks to their proportional response, their good efficiency and spectral range, and their better sensibility, and signal to noise ratio, both enhanced by the gain. As a consequence, LGAD is going to populate the timing layers of both the ATLAS and CMS timing layers at the HL-LHC. This presentation looks at how the LGAD concept can be adapted to overcome the future challenges on particle detection. Specifically, we will show IMB-CNM advances on the inverse and trench-isolated inverse LGAD designs, conceived to overcome the small pixel problem; the engineering of the multiplication layer profiles, to enhance the LGAD response under high fluence irradiation, as well as the new designs oriented to the detection on the soft x-ray or deep UV domain.
