低能强流电子加速器的研制

Development of a High-current Electron Accelerator with Low Energy

中国科学院近代物理研究所在现有DG系列电子加速器技术的基础上,通过改进加速结构,研制了一台低能强流电子加速器,其设计指标为500 keV/150 mA。该加速器采用高压发生器倒置的结构,并增加了中磁圆盘,提高了电能转换效率。采用了较短的加速管结构,有利于强流电子束的传输,同时使加速器整体更为紧凑。加速器束流调试结果为500 kV/170 mA,完全优于设计指标。

Based on the technology of the DG series electron accelerator, a 500 kV/150 mA electron acceler- ator was designed and manufactured at IMP（Institute of Modern Physics, Chinese Academy of Sciences）. The new structure of high voltage and shorter accelerating tube have been used in this accelerator for high current. The specific features of this accelerator are compact of structure and higher power conversion efficiency. It has already passed the running test of 500 kV/170 mA, and the parameter is better than the designed value.
