Abstract:

Space radiation can increase the noise of photodiodes as a result of either a sustained ionizing dose rate effect or displacement damage. Elementary, straightforward models are presented for calculating radiation threshold levels and rad hit susceptibility. Radiation-effects experiments that verify these models are discussed. Calculations for room-temperature silicon p-i-n photodetectors, an avalanche photodiode, and a hypothetical cooled staring detector indicate that this damage mechanism should not be ignored for space and nuclear environments. Keywords include Noise Photodiodes Radiation effects and Space radiation.
