High inductive helical support provides a solution to controlling the alignment error of inner electrodes in magnetically insulated transmission lines (MITLs). Three-dimensional particle-in-cell simulations were performed to examine the current loss mechanism and the effects of structural parameters on electron flow in an MITL with a helical inductor. An empirical expression related to the ratio of electron current loss to anode current and the ratio of anode current to self-limited current was obtained. Electron current loss caused by helical inductor with different structures was displayed. The results indicate that the current loss in an MITL, near an inductive helical support, comprises both the inductor current and the electron current loss. The non-uniform structure and current of a helical inductor cause an abrupt change in the magnetic field near the helical support, which leads to anomalous behavior and current loss of electron flow. In addition, current loss in the inductive helical-supported MITL is negligible when the inductance of the support is sufficiently high. This work facilitates the estimation of electron current loss caused by the inductive helical support in MITLs.

带有感应螺旋支撑的磁绝缘传输线中电流损耗的粒子模拟

高电感螺旋支撑为控制磁绝缘传输线（MITL）中内部电极的对准误差提供了一种解决方案。进行了三维粒子模拟，以检查电流损耗机理以及结构参数对带有螺旋电感的MITL中电子流动的影响。获得了与电子电流损耗与阳极电流之比以及阳极电流与自限电流之比有关的经验表达式。显示了由具有不同结构的螺旋电感器引起的电子电流损耗。结果表明，在感应螺旋支撑附近的MITL中的电流损耗包括电感器电流和电子电流损耗。螺旋电感器的不均匀结构和电流会导致螺旋支撑附近磁场的突然变化，从而导致异常行为和电子流的电流损耗。另外，当支撑的电感足够高时，电感螺旋支撑的MITL中的电流损耗可以忽略不计。这项工作有助于估算由MITL中的感应螺旋支撑引起的电子电流损耗。
