为了方便地测量封有内靶的高能电子加速器束斑 ,采用了一种基于厚针孔成像技术的动态监测系统 .本文给出了采用该系统在 15MeV电子直线加速器束流打靶后的束斑测试结果 ,并简要介绍了成像原理和处理办法 .通常的“三明治”方法需要冲洗X光胶片 ,整机调试时更要多次冲洗 ,效率较低 .与之相比厚针孔成像方法可以实时成像 ,配合调机及时观察束斑的变化情况 ,使加速器参数调整有的放矢 ,提高了调机效率 . In order to conveniently measure the beam spot of the high energy electron accelerator enclosed by the target, a dynamic monitoring system based on the thick pinhole imaging technology is presented.In this paper, the beam spot test of the 15 MeV electron linear accelerator Results and brief introduction to the imaging principle and treatment methods. The usual “sandwich” method requires washing X-ray film, the whole machine when debugging more washed more inefficient.In contrast with thick pinhole imaging methods can be real-time imaging , In time with the transfer machine to observe changes in beam spot, so that the accelerator parameters to be targeted, improve the efficiency of the machine.
