Soft X-ray source with cylindrical plasma compression

摘要

Intense soft X-ray source comprising a means for producing a cylindrical plasma jet between a cathode and an anode, connected to a pulsed high voltage generator, wherein the means for producing the plasma jet comprises a capacitor bank connected to a charging voltage source and also to a transmission line provided with a tripping means, the assembly having a very low inductance so as to permit a rapid discharge; a sheet of solid material connected by its periphery to one of the conductors of the line and by its central part to the other conductor, so that a radial discharge can be produced when the tripping means is conductive, a plasma jet resulting from the explosion of the sheet; a means for giving the said plasma jet a cylindrical shape.
