Several theories exist to explain persistence, most of which revolve around the distribution of traps. We aim to simulate persistence and illustrate this complex issue with a 3D trap map. For this experiment, we vary the detector voltage bias to simulate the change in the depletion region that occurs when the detector is exposed to light. This allows us to measure the distribution of traps in the depletion region. This paper will explore the results from this experiment and discuss the implications.

  1. Assessing the Suitability of H4RG Near Infrared Detectors for Precise Doppler Radial Velocity Measurements

    astro-ph.IM 2019-08 conditional novelty 6.0 of 10

    Simulated H4RG detector noise sources translate to radial velocity errors of 0.32 to 3.5 m/s in quadrature, suggesting sub-m/s precision is possible if persistence and nonlinearity are controlled.

  2. Performance of the image persistence model for Euclid infrared detectors

    astro-ph.IM 2025-06 conditional novelty 5.0 of 10

    A power-law model with six per-pixel parameters describes image persistence in Euclid's NISP detectors with residuals of a few electrons, but the accuracy is mostly measured on the fitting data.
