A Theoretical Study of the Effect of Discharge Parameters on the Plasma Layer in a Filippov Type Plasma Focus Device

Abstract

In this paper, the theoretical ML model has been used to study the effect of three preliminary parameters (gas pressure, discharge voltage and the kind of the gas), to the current, azimuthal magnetic flux density, and the plasma layer pressure, in the Filippov type plasma focus device, Dena. Among others, it has been shown that to have an optimum pinch, the mentioned parameters should be selected in a manner so that the plasma sheath moves with an optimum velocity. A higher or lower velocity leads to pinch formation in an inappropriate time, when the plasma pressure is relatively low.
