Abstract
This paper presents the results of tests of a facility based on a ten-element disk magnetocumulative generator and an explosive opening switch. A current of 10 MA with a characteristic rise time of ≈0.5 μs was obtained by breaking a circuit with a current of 18 MA in a load with an inductance of 16 nH, which is equivalent to the inductance of the chamber with a multiwire liner.
