Test of Device Based on Disk Magnetocumulative Generator DMCG480 With Explosive Current Opening Switch

One of the perspective directions in high-energy-density physics is the creation of powerful electro physical facilities capable to form megampere current pulses with short front. This paper presents test results of the device based on five-element disk magnetocumulative generator DMCG480 and an explosive current opening switch. The current pulse of 15 MA with characteristic rise time of ~0.8 μs was obtained in the equivalent multiwire array load of 17 nH at circuit breaking with the current of 32 MA.

I. Introduction

Megampere current pulses with the rise time at least 0.5 are necessary to obtain high energy density in the liner experiments of the soft X-rays pulse generation [1].
