星用紫外线阵CCD抗辐照性能的地面模拟试验与验证

Ground simulation and experiment on ultraviolet linear CCD Anti-irradiation performance used by satellite

摘要:

航天用CCD器件由于其工作环境的特殊性，有抗辐照能力的特殊要求。根据星用系统的要求，设计并制作了一款满足航天要求的全定制的紫外线阵CCD。该款CCD通过抗辐射加固技术设计，具有高紫外量子效率、大满阱容量、大动态范围的特点。紫外线阵CCD经过抗辐射加固的优化，最终产品通过了可靠性试验的考核，承受了30k rad（Si）的总剂量辐照和5.0×109质子/cm2的位移效应辐照，试验后仍满足型号卫星的全部要求，该卫星已于2018年9月份成功发射，目前在轨工作状态良好。

Abstract:

Because of the special work environment the spaceflight Charge-Coupled-Device (CCD) has the demand of Anti-irradiation performance. A customized ultraviolet linear CCD was designed and manufactured to satisfy the needs of satellite system. The CCD based on the development of anti-irradiation and reinforce technology, as well as have the characteristics of high quantum efficiency, high full-well capacity and large dynamic range. After experience several times optimization, the ultraviolet linear CCD had pass the reliability experiment. The performance test indicates that the CCD’s performance always meet the demand of satellite after it endures 30k rad(Si) total dose radiation and 5.0×109 proton/cm2 displacement damage effect. And now, the satellite system is running well on its orbit around the earth since it has been already successfully launched in September 2018.
