Application of radiation sources to simulate the radiation environment in low earth orbit: results on optoelectronic devices for International Space Station

There is a trend toward evaluating the space worthiness of electronic devices under conditions that simulate the intended operating environment of the spacecraft as much as possible. We briefly discuss simulation of space radiation environments using various ground based radiation sources. As a specific example, we present the radiation evaluation of two optoelectronic devices to be used on the International Space Station under proton irradiation designed to simulate the low earth orbit environment.
