介绍了变像管扫描相机对直线感应加速器注入器中的电子束束剖面直径的应用。获得了由注入器产生电子束 (电流 2～ 3kA)经 0 5mm厚石英玻璃产生的契伦柯夫辐射的扫描像。对拍摄到的扫描像进行了图像处理和数据分析 ,得到了电子束直径随时间变化的曲线图
The application of image tube scanning camera to electron beam profile diameter in linear accelerator accelerator is introduced. A scanning image of the Cherenkov radiation generated by the injector with an electron beam (current 2 to 3 kA) through a 0 to 5 mm thick quartz glass was obtained. Image processing and data analysis are performed on the scanned image, and the graph of the diameter of the electron beam with time is obtained
