摘要

在ESA的EarthCARE任务中，ULIS UL03041热红外图像传感器进行了钴60和重离子辐照，以评估其可靠性。器件测试高达10 krad(Si)和40 MeV/mg/cm2 LET。该传感器具有可接受的性能，至少可达10克拉(Si)，并且易受SEL影响，低至15.9 MeV/mg/cm2，估计阈值为12.1 MeV/mg/cm2。

Radiation Effects in Thermal Image Sensors for Earth Observation Missions

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.
