Gamma ray damage of biased CCD image sensors

High image quality CCD image sensors are needed in many applications. Low noise and high dynamic range are critical parameters required in scientific and industrial applications. In many of the applications, however, the CCD image sensor can be irradiated by an ionizing radiation, as alpha, beta, gamma or X-ray. This paper shows behaviour of low noise, high dynamic range, 1 megapixel frame transfer CCD FTT1010-M image sensor radiated by gamma ray radiation. CCD image sensor driver board with rad-hard components was designed and used during the tests. Results of the investigation will be used in system for protein crystallization study in microgravity.
