介绍了“聚龙一号”中四层圆盘锥磁绝缘传输线(MITL)的基本理论。在CPIPIC平台上,采用非均匀网格和周期性对称边界条件,建立了“聚龙一号”的四层圆盘锥MITL的三维粒子模拟模型。设置相应的参数并用并行算法模拟得到了该器件中各层在绝缘堆上和MITL中间位置的电流和汇流后的电流,并与理论和实验数据进行相互对比验证。模拟结果表明整个器件在达到磁绝缘状态后具有很高的传输效率,并与实验结果相互验证,为以后进一步的研究提供了保证。
The basic theory of a four-level coaxial circular-cone magnetically-insulated transmission line for“Julong-1”is introduced. A 3-D particle simulation model for the four-level circular cone MITL of“JuLong-1”was set up on the platform of CHIPIC by using the non-uniform grid and periodic symmetric boundary conditions. The current in each layer on the insulation heap and in the middle of MITL,and the confluent current were obtained through the corresponding parameter setting and simu-lation with the parallel algorithm. The comparison results of theoretical and experimental data show that the whole device has the very high transmission efficiency after reaching magnetic insulation condition,which provide a guarantee for the further study.
