紧凑型静电加速管的原理设计

Design of a Novel Compact Electrostatic Accelerator Cube

提出了利用紧凑型静电加速管对强流相对论电子束进行加速的概念。通过理论分析及粒子模拟,对1kA、500kV的初始入射电子束,在约0.8m的加速段加速使其达到10MeV,在没有聚束磁场的前提下电子束可以得到传输和加速。通过优化设计可使加速腔的最大场强降为20MV?m?1。

This paper presents a novel conception that intense relativstic electron beam is accelerated by compact electrostatic accelerator cube. According to the theoretic analysis and PIC, the electron beam with current 1 kA and initial voltage 500 kV is accelerated in the accelerator of 0.8 m and it becomes 10 MeV. The beam is transported and accelerated without focusing magnetic field. The biggest electronic field can be decreased 20 MV/m by optimization design.
