Avalanche Photodiode Arrays Enable Large-Area Measurements of Medium-Energy Electrons


We demonstrate the performance of a large-area avalanche photodiode array as a medium-energy electron detector. This avalanche photodiode array is composed of eight pixels with 1.2 cm2 of total active area. The energy resolution (DeltaE/E) is as low as 4.5% in full width at half maximum for 25-keV electrons, and the linearity is excellent. Monte Carlo… (More)
