Opening Switch Research on a Plasma Focus VI.

Abstract

The utility of the plasma focus as an opening switch was analyzed on the basis of our previous experimental observations and those on other Mather-type devices, A load resistor has recently been included in the opening switch circuit model and the analysis indicates that the typical pinch resistances measured (approx .1ohm) are too small to drive typical load resistances encountered in pulsed power (approx 1ohm) in terms of % energy transferred (<2%) and the time required for the transfer (> or = 200ns). A scaling law for pinch stability has been derived, which is consistent with our data and that from several other experimental devices; this model predicts that a plasma focus could be designed to permit longer energy transfer times by increasing the anode radius. Keywords: Dense plasma focus, Soft xray spectroscopy, Laser interferometry, Opening switch research, Soft xrays. (MJM).
