Paper Abstract

Since the pioneer work of J.J. Rocca et al. in the development of discharge pumped soft X-ray lasers, different experimental setup have been proposed at fast capillary discharge drivers. At GREMI, we developed a fast high voltage pulsed generator driving a Z-pinch capillary discharge capable of producing a plasma highly emissive in XUV. This work reports on the study of a Blumlein Pulse Forming Line generator. A model has been developed for a better understanding of produced currents. Comparison between experimental and calculated current waveforms show a good agreement. Short rate of rise time pulses as high as 1.2 X 1012 A(DOT)s-1 have been achieved. Modeling of the discharge led to the conclusion that a Z- pinch effect could occur. Argon time-integrated spectra showed that highly ionized argon lines, up to Ar XII, have been produced.
