Resumo

The article presents the results of experiments and radiation magnetohydrodynamic simulations of the electrical explosion of flat copper conductors in megagauss magnetic fields. The experiments were carried out on the terawatt-range MIG generator at the current of amplitude up to 2.5 MA and the rise time of 100 ns. The thickness (along the y-axis) of the conductors used was much less than theirs width (along the x-axis) and the current flowed in the z-axis. It was experimentally shown and confirmed by RMGD simulations, that the conductor expands in thickness (along the Mi>y-axis), while plasma expansion along the x-axis is suppressed. This is due to the increased magnetic field at the conductor edges, which also causes earlier explosion of the side faces. A matter from the side faces, that is low-density plasma, flows toward the center of symmetry of the wide faces of the plate. As a result, a plasma channel forms on the wide face of the conductor (at the xz plane) along z-axis about 75 ns after the onset of current flow. X-ray patterns of the conductors were obtained with radiation from the X -pinch “hot spot”. The recorded expansion of the conductor along the y-axis is in good agreement with the results of numerical simulations.
