Runaway of the front of a shock wave near a metallic surface, and mechanism of the destruction on the current sheath in a noncylindrical Z-pinch
Velikovich A.L., Liberman M.A.
It is shown that heating the surface of an anode and of a gas layer adjacent to it by radiation of a current sheath is the cause of the runaway of part of the current-sheath front adjacent to the anode. The evolution of this process is also the cause of the destruction of the current sheath of the plasma focus.
