等离子体碎片加速器的放电电流测量

Measurement of the discharging current of the plasma dynamic accelerator

基于最新研制的脉冲运行装置——等离子体驱动微小碎片加速器的诊断需求,设计了罗科夫斯基线圈及其信号处理电路;对线圈的测量原理、线圈结构及电子线路方案设计、静电屏蔽等环节进行了详细分析和介绍,并对测量结果结合线路理论进行了分析和验证,同时对误差来源进行了讨论.

A Rogowski coil has been designed to measure the discharging current of the plasma dynamic accelerator which has been developed recently. The principle of Rogowski coil for measuring pulse currents, the electric and geometric parameters of the coil and the ways to shield the coil from the electromagnetic interference have been analyzed. The measuring results have been presented and verified according to the theory of the circuit, and the elementary analysis of the source of the error has been done.
