Description
Low Gain Avalanche Detectors (LGADs) have recently emerged as key sensors for precise timing measurements, enabling accurate tracking of charged particles and photons in High Energy Physics (HEP) experiments and beyond. The time resolution is closely linked to the detector's gain, with a direct correlation between gain stability and timing precision. In turn, the gain of LGADs depends on the nature of the particle being detected, since both the ionization density and the depth at which the charge is generated within the active volume influence the multiplication process, a phenomenon known as gain suppression. This contribution presents gain suppression studies performed on LGAD detectors fabricated at IMB-CNM, employing Ion Beam Induced Current (IBIC) measurements with a focused 2.3 MeV proton microbeam at different incidence angles. The analysis provides direct insight into the spatial dependence of charge multiplication and highlights the sensitivity of LGAD performance to different ionization density profiles.
