Abstract

A facility capable of producing very high gamma flux levels and rapid total dose accumulation for testing infrared detectors and multiplexed hybrid arrays has been developed. Effective gamma fluxes from 108 to 1014 gamma/cm2-sec equivalent are routinely achieved. Total dose testing has been performed on various devices at rates between 0.5 rads(Si)/second and 50,000 rads(Si)/second. Testing has been performed at temperatures between 5K and 77K and optical backgrounds as low as 1 • 1011 photons/cm2-sec. In addition to the electron beam, a low level gamma source facility and complete electronics test suite are described. Data will be presented for several types of detectors and hybrids to demonstrate test capabilities and device response.
