针对Kodak公司的商用CCD探测器KLI-2113进行了总剂量为30 krad(Si)的60Co-γ辐射试验。对比辐射前后CCD的主要参数变化, 分析了总剂量辐射对CCD工作性能的影响, 并研究了总剂量辐射导致CCD暗电流增大、电荷转移效率降低以及图像噪声增加等现象的内在机理, 为后续CCD抗总剂量辐射加固提供依据和参考。

This paper researched the Cobalt 60-γ total dose radiation test for the CCD KLI-2113 from Kodak Company by comparing the main parameters shift before and after radiation.The effect of the total dose radiation on the performance of CCD was analyzed. The results indicate that the radiation induces the increase of the dark current, the decrease of charge transfer efficiency, the increase of picture noise. There result provides reference for the total dose resistant radiation hardening in future.
