Abstract

In this paper, Ni-Zn ferrite loaded coaxial line, using oil as insulation, with subnanosecond rise time at the input pulse voltage up to 360 kV into a 50 load is described. The dependence of the shock front development on the line length and pulse voltage was investigated. The experimental data were compared with analytical predictions of early theory. The experimental and expected results are shown to be in quite good agreement. A modified ferrite-loaded line with lower impedance was fabricated in order to increase its magnetic field. The ferrite loaded line showed stable work at pulse repetition frequency of 100 Hz and the shortest rise time of 0.7 ns has been achieved. Benson et al have proposed to use an axial magnetic field bias for further pulse sharpening. Magnetic bias conditions for the optimal pulse sharpening were tested.
铁氧体负载同轴线路中高压脉冲的亚纳秒级上升时间
本文介绍了一种以油为绝缘材料的镍锌铁氧体负载同轴线路,该线路在输入脉冲电压高达360 kV时上升时间达亚纳秒。研究了激波前沿发展与线长和脉冲电压的关系。实验数据与早期理论的分析预测进行了比较。实验结果与预期结果吻合较好。为了提高铁氧体负载线的磁场强度,制备了一种具有较低阻抗的改性铁氧体负载线。铁氧体负载线在脉冲重复频率为100 Hz时工作稳定,上升时间最短为0.7 ns。Benson等人提出使用轴向磁场偏置进一步的脉冲锐化。测试了最佳脉冲锐化的偏磁条件。
