We present the design and parameters of a compact and mobile high-current pulse generator, which can be applied in the study of warm dense matter in university laboratories. The generator dimensions are 550 × 570 × 590 mm³, the weight is ∼70 kg, and it consists of four “bricks” connected in parallel. Each brick, made up of 2 × 40 nF, 100 kV low-inductance capacitors connected in parallel, has its own multi-gap and multichannel ball gas spark switch, triggered via a capacitively coupled triggering by a positive polarity pulse of ∼80 kV amplitude and ∼15 ns rise time. At a charging voltage of ∼70 kV, the generator produces a ∼155 kA current pulse with a rise time of ∼220 ns on a ∼15 nH inductive short-circuit load and a ∼90 kA amplitude current pulse in the underwater electrical explosion of a copper wire.

紧凑型高电流脉冲发生器，用于高能量密度物质的实验室研究

我们介绍了一种紧凑的移动式大电流脉冲发生器的设计和参数，可将其用于大学实验室中的热致密物质的研究。发电机尺寸为550×570×590 mm ³，重量约为70 kg，由四个并联的“砖”组成。每块积木由2×40 nF，并联的100 kV低电感电容器组成，具有自己的多间隙和多通道球形气体火花开关，通过电容耦合触发，振幅为80 kV左右的正极性脉冲触发上升时间约为15 ns。在〜70 kV的充电电压下，在水下电磁爆炸中，发电机在约15 nH的感应短路负载下产生约155 KA的电流脉冲，上升时间约为220 ns，振幅电流脉冲在约90 KA的情况下产生。铜线。
