Rockwell H1RG silicon PIN diode array gamma and proton radiation characterization at cryo temperatures

The Rockwell Scientific Company, HAWAII-1RG PIN silicon diode array, designed for high performance, low noise applications in ground-based astronomy, has been tested for suitability in space application ranging over a wide selection of orbits. Gamma testing for total ionizing dose (TID) effects in the read out integrated circuit (ROIC) and proton transient and damage testing to characterize the PIN diode response were performed at a range of cryo temperatures. At high damage levels, annealing rates at cryo-temperature were measured. The physical responses are used to develop first-principles physics models useful for predicting and simulating the H1RG performance in orbits of interest for the proposed mission(s).
