Annealing of radiation damage in InGaAs vSWIR imaging sensors

The InGaAs photodetector used in the VEM and VenSpec-M instruments for NASA’s VERITAS and ESA’s EnVision missions has shown high potential for moderate temperature annealing during our space environment qualification campaign. We propose an annealing scenario that could be applied to the detector and incorporates estimations for galactic cosmic rays (GCR) and solar energetic particles (SEP) events, which are the main causes of increased noise and thus reduced image SNR.
