| 中文摘要 | 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 easily measure the beam spot size of high energy electron accelerators with internal target enclosed, a real-time system, based on thick pinhole imaging technique, is employed. The experimental result on a 15MeV electron linear accelerator is also presented. In this paper the principle of thick pinhole imaging and the processing of data are introduced. The usual “sandwich” method needs to develop X-ray films, while debugging the accelerator parameters it will take a lot of time. On the contrary, X-ray pinhole imaging method can make a real-time measuring: as the accelerator parameters change, we can observe the beam profile’s variation on the computer screen. Then when debugging we can have a definite object in view, and adjust the accelerator parameters more efficiently.; 国家自然科学基金 (10 13 5 0 40 )资助~~ |
