| 摘 要： | 根据220 GHz回旋管的工作要求，设计了其所需的脉冲磁场系统与电子枪。脉冲磁场系统采用哑铃状结构，具有均匀区长、电阻小与电感小等优点，可以在较低电容与电压下获得更高的脉冲峰值磁场，并分析了其脉冲放电特性。电子枪采用双阳极磁控注入枪，用EGUN对其进行了设计优化，电子注纵横速度比为1.53，速度零散为3.1%。实验研究表明，脉冲磁场峰值强度达到8 T，电子注电流达到2 A，电子电流基本传输到靶片，控制极与阳极没有截获到电子，脉冲磁场系统与电子枪工作正常，达到设计要求。

| Abstract: | According to the requirement of 220 GHz gyrotron designed by University of Science and Technology of China, a pulsed magnet system and electron gun have been designed. The pulsed magnet system is dumbbell-shaped with the advantages of long uniform district, little resistance and inductance. It can obtain a high peak pulsed magnetic field with small inductor and capacitor. A double-anode magnetron injection gun has been designed and optimized by EGUN for the gyrotron. The electron beam velocity ratio is 1.53, and the velocity spread is 3.1%. The experimental results show that, the peak magnet field of the pulsed magnet system was 8 T, the electron beam current reached 2 A, the electrons were transported to the target, and few electrons were not sent to the control anode and anode, which mea |
