Abstract

The paper presents the results of an experimental study of the skin explosion of cylindrical conductors of diameter 1-3 mm (copper, aluminum, titanium, steel 3, and stainless steel) at a peak magnetic field of 200-600 T. The experiments were carried out on the MIG pulsed power generator at a current of up to 2.5 MA and a current rise time of 100 ns. The surface explosion of a conductor was identified by the appearance of a flash of extreme ultraviolet radiation. A minimum magnetic induction has been determined below which no plasma is generated at the conductor surface. For copper, aluminum, steel 3, titanium, and stainless steel, the minimum magnetic induction has been estimated to be (to within 10%) 375, 270, 280, 220, and 245 T, respectively.
