Characteristics of the Hubble space telescope's radiation environment inferred from charge--collection modeling of near-infrared camera and multi-object spectrometer darkframes

Dark frames from orbiting infrared detector arrays are analyzed using a charge-collection model to investigate the effects of secondary and primary particle environments in infrared detectors and related electronics. The effects of different components of the primary and secondary environments are assessed by examining trends with time and pixel-to-pixel charge correlations.
