摘要
研究了电荷耦合器件(CCD)位移辐射效应的损伤机理。分析了位移损伤诱发的体缺陷对CCD工作性能的影响。研究了位移损伤导致CCD电荷转移效率降低、体暗电流密度增大、暗电流尖峰以及随机电码信号(RTS)出现的规律和机理。
The displacement damage mechanism of radiation effects in charge coupled devices(CCD) is researched. It is analyzed that the displacement radiation damage induces the generation of bulk defects which degrade the performance of CCD. Displacement radiation damage induces the decrease of charge transfer efficiency, the increase of the bulk dark current , and the generation of dark current spikes and random telegraph signal(RTS).
