摘要

对永磁电子回旋共振（Electron cyclotron resonance

ECR）离子源磁场运用Poisson程序进行了模拟计算

将模拟计算结果和测量结果进行了比较。依据计算结果

设计加工了NdFeB（钕铁硼）永磁体

得到了比较好的磁场场形

并在ECR离子源调试中获得了较强的束流。

Abstract

The calculation of permanent magnet for ECR ion source with Poisson code has been completed and compared with the experiment results. Based on the calculation

a permanent magnet made of NdFeB has been designed

which is availed to get high current ion beam with the ECR ion source.
