Abstract

MHD compression of a heterogeneous Z-pinch produced by the explosion of a thin metal wire in the diode of a high-power current generator is investigated. The process is calculated starting from the instant when the breakdown of the evaporation products from the metal surface has come to an end and the current is just switched from the central core to the surrounding plasma corona, whereas the core material is still in the liquid-vapor state. The influence of the cold core on the plasma implosion is studied. The results obtained are compared with similar calculations carried out under the assumption that, in the initial state, either the core material is completely ionized or the core is absent at all.
