Paper Abstract

The effect of 30 MeV electron irradiWon op InGaA LEDs and InGaAs photodiodes was studied. Electron fluxes ranged from 1012 e/cm2 to 1015 e/cm2. The beam profile was measured with an improved scanning wire technique. During irradiation, light output, total current, and temperature were monitored for the LEDs. Responsivity and temperature were monitored for the photodiodes. Spectral characteristics and current-voltage curves were measured before and after irradiations. Changes in photodiode dark current were observed and LED lifetime-damage constant products were computed.
