Possible mechanism of breaking the current sheath in a noncylindrical z-pinch
Bazdenkov S. V. , Gureev K.G., Filippov N.V., Filippova T.N.
In a number of experiments devoted to the "plasma focus" in the "MG" apparatus [1] it was observed that when working with a mixture of detuerium with a heavy gas (e.g., 0.3 1% Xe), the current sheath is disrupted ("breaks") in the anode region as it moves towards the axis of the chamber. The current sheath breaks at relatively large distances (8 15 cm) from the axis, commensurate with the anode diameter. The deuterium pressure in these experiments is 0.3-1 Torr, the discharge current at the instant of the break is ^ 1 mA, and the capacitor-bank voltage is 16 18 kV.
