  • Abstract
    Cobalt60 and heavy ion irradiations of the ULIS UL03041 thermal infrared image sensor were performed to assess its reliability during ESA´s EarthCARE mission. Devices were tested up to 10 krad(Si) and 40 MeV/mg/cm2 LET. The sensors have acceptable performance up to at least 10 krad(Si) and are susceptible to SEL down to a LETs of 15.9 MeV/mg/cm2 with an estimated threshold at 12.1 MeV/mg/cm2.
