GaAs Displacement Damage Dosimeter Based on Diode Dark Currents


GaAs diode dark currents are correlated over a very large proton energy range as a function of displacement damage dose (DDD). The linearity of the dark current increase with DDD over a wide range of applied voltage bias deems this device an excellent candidate for a DD dosimeter. Additional proton testing performed in situ enabled error estimate… (More)
