深入阐述了拥有自主知识产权的粒子模拟-蒙特卡罗算法, 并采用该算法数值研究了J-PARC多峰离子源放电特性, 分析了J-PARC离子源的放电机理, 并在单、双校正磁体下讨论了该离子源体积产生效率. 结果显示: 在单校正磁体下, 校正磁体中心与离子源顶端相距50 mm时, 体积产生效率最大; 在双校正磁体且固定顶端磁体下, 两磁体相距越大体积产生效率越低.

In this paper, the particle-in-cell/Monte Carlo method simulation algorithm with independent intellectual property is described in-depth. The discharge properties of the J-PARC multicusp ion source are investigated using this algorithm. The discharge mechanism of the J-PARC ion source is discussed, and the ion source volume production efficiency is analyzed under single correction magnet and double correction magnets. The results show that under the single correction magnet, a maximum volume production efficiency can be obtained when the distance between the center of the correction magnet and the top of the ion source is 50 mm; fixed the top one of double correction magnet, the longer the distance between magnets, the lower the volume production efficiency is.-
