Plasma-Beam-Hole Interaction

Highly energetic and dense plasma beams obtained by an improved version of a coaxial gun were directed towards a perforated metallic plate to study plasma-hole interactions. The features of the escaping plasma jet were studied by means of the method of characteristics applied to a single fluid flow. The incident plasma beam and the characteristics of the escaping jet were investigated by means of various diagnostic techniques. Observations provided evidence that a large amount of material was ablated from the hole region and transported by the escaping jet.
