Linear transformer driven long pulse high power generator with higher repetition rate

阐述了长脉冲高功率微波驱动源模块化的实现思想,分析了快直线变压器的铁磁损耗与激磁电流之间的关系,研究了系统输出波形畸变的主要因素,并通过工程实验取得了功率为数GW、重复频率为数十Hz、脉冲前沿约40ns的长脉冲电子束流输出,从而为重复频率长脉冲模块化高功率微波驱动源的研制提供了新思路.

The realization technique of modularization on the long pulse high power generator was expounded.The relation between the ferromagnetic dissipation of the linear transformer and the exciting magnetic current was analyzed.The main influential factors on the wave distortion from the primary pulse to the system output waveforms were discussed.Finally,through engineering experiments,a long pulse power electron beam of up to several gigawatt with repetition frequency of several dozen hertz and rise time of 40—50 ns was obtained.This paper gives a new idea for research on the modularization of the long pulse high power generator with higher repetition rate.
