Abstract : During the first year of the research program on the use of a plasma focus machine (PF) as a M Amp opening switch we have: (A) Improved the performance of our presently functioning system by finding a new method of increasing the surge of anamalous (i.e., noncollisional) resistivity which controls the switch opening function (specifically, the rate of disintergration of the PF pinch where the current is concentrated). (B) Devised new methods to monitor the rate of disintegration of the PF pinch via the changes of the particle emission spectra as a function of time (on a nanosec scale) and of position (on a 50 micrometer scale) inside the pinch. (C) Made substantial progress in the construction of an upgraded system which can operate at higher current levels as compared to the present 0.5 - 0.7 MA. (Author)
