Abstract

A wide area x-ray generator working at relatively low pulsed voltage was carried out in order to preionize an HF laser discharge. This x-ray source is based on the use of a corona plasma cathode. With this device, preionization densities of about 10⁸/cm³ in 1 bar argon and of approximately 10⁷/cm³ in the 110 Torr laser mixture were obtained for a 30 ns FWHM x-ray pulse duration (corresponding to approximately 4 J of input energy). The operating characteristics of this corona x-ray generator are presented, as are the preliminary results on the x-ray preionization of the HF chemical laser.
