Result of curretn flow with a linear density of 1–3 MA/CM and duration of 100 NS across stainless steel electrodes

When the current has a linear density of 1–3 MA/cm and duration of 100 ns the diffusion of the magnetic field deep into the electrode is complicated by heating the metal and the formation of the plasma on the surface. A series of experiments on the transmission of current with a rise time of 100 ns and amplitude of about 3 MA across stainless steel electrodes was conducted on the Angara-5-1 facility. The electrodes were hollow tubes with a wall thickness of 1 mm. The diameters of the tubes were 3 mm and 12 mm.
