摘要: 基于“晨光号”X光机开展了可见光条纹相机在复杂的辐射/电磁环境中的可靠性实验研究。利用序列脉冲激光的成像状态表征条纹相机的扫描状态，采取了不同的辐射/电磁防护措施，研究其对扫描状态的影响。实验研究获得了该类相机在此类复杂环境中正常工作的防护方法，主要包括增强辐射屏蔽使条纹相机附近的单发次等效空气吸收剂量不超过6 μGy、减少相机机壳的缝隙、采取光电隔离的触发方式等。Abstract: The reliability of optical streak camera in the environment of extreme radiation and electromagnetic field has been investigated on “Chenguang” Accelerator. The image of a series of pulse laser was used to indicate the scanning status of the streak camera. The influence of different manners of radiant and electromagnetic shield has been explored. At last, the conditions of this kind of streak camera working normally in these extreme environments were gained in this experiment: enhancing radiation shield to reduce the equivalent air absorbed dose of single shot near the streak camera to 6 μGy, reducing the outer covering gaps of the streak camera, using photoelectric trigger and so on.
