Why (and How) LGADs Work: Ionization, Space Charge, and Gain Saturation

N. Cartiglia, A. R. Altamura, R. Arcidiacono +10

The temporal resolution of Low-Gain Avalanche Detectors (LGADs), also known as Ultra-Fast Silicon Detectors (UFSDs), is governed by two contributions: jitter, arising from electron…
