Experiments on cumulative jets current destruction

Summary form only given, as follows. At the experiments, earlier performed by the authors, on metal cumulative jets destruction with the current of capacitor banks, almost complete destruction of the whole jet was achieved. In this case cumulative charge was located at a distance from the current electrodes, approximately equal to the diameter of cumulative crater. The physical picture of the jet destruction in the high-current regime lies in the initial development of instabilities in a MHD jet in the form of necks and further electrical explosion of these necks. Similar experiments at increased distances between the cumulative charge and electrodes are described. It is shown that the results of cumulative jet destruction could become worse, since change of the initial state of the jet changes the physical picture of its current destruction process.
