Physical processes of the interaction of ion and plasma streams with a target surface in a dense plasma focus device

Abstract

Dynamics of the interaction of powerful streams of high-temperature plasma and fast ions generated in a device of the “Dense Plasma Focus” (DPF) type has been studied for a special case. In these experiments solid conductive targets with the shape of a plate and a tube, respectively, were placed normally and axially with respect to the Z axis of the DPF chamber on its cathode side. The secondary plasma spread out from the target surface has been examined. The shock-wave action upon the flat targets produced by the ion beam has been revealed.
