-
摘要: 介绍了用多孔板—荧光屏与双孔准直器—Rogowski线圈相结合的方法,测量强流脉冲电子束发射度与亮度的实验研究工作。利用摄像机及图象数据微机处理系统,实现了实时测量。对国防科技大学的81—7M—O1强流脉冲电子束进行了实际测量,得到了其非规一化的边发射度为361cm·mrad,亮度为1283A·cm-2·rad-2的初步结果。Abstract: The experimental study of emittance and brightness measurement for pulsed intense e-beam using the combination of so called "pepperpot-screen"and "two-aperture collimator-Rogowski coil" are described. Real time measurements are realized with a camera and data processing system. A non-normalized emittance of ε2.90 = 361cm·mrad and brightness of B90= 1283A·cm2·rad-2 are obtained for the pulsed e-beam of 81-7M-01 accelerator in the National University of Defense Technology.
