Study of the plasma focus as a driver for the magnetic compression of liners

Possibilities of plasma focus - type facilities using in investigations on high density energy physics are discussed. The experimental results of studying wire arrays compression by PF-3 plasma focus facility current sheath performed in Kurchatov Institute are given. The technology of manufacturing the liners has been developed at TRINITI. Compression of the tungsten wire arrays having linear mass 0.33–0.6 mg/cm with velocity ∼(2÷3)×l0
⁶
cm/s are shown. A new approach to forming liner load is proposed. Such load represent an ensemble of free fine-disperse particles of substance (dust). A given approach has some advantages related, first of all, with an opportunity to vary - on a wide scale - the mass, configuration and the element structure of a similar liner. In the first experiments at PF-3 facility an efficiency of interaction between the PF-sheath and the dust target has been shown that is manifested, in particular, in the enhanced MHD-pinch stability.
