Abstract

A measurement system for proton radiation effects in light emitting devices such as light emitting diodes and semiconductor lasers are described. 10-MeV and 200-MeV proton beams in the Wakasawan Energy Research Center are utilized. Current vs. voltage characteristics, current vs. light output characteristics and spectra can be measured using an integration sphere, a Si photodiode, a data logger and a spectrometer. In the case of 200-MeV irradiation, remote measurement is conducted.
