Discharges in argon-filled capillaries at currents between 20 and 60 kA produced plasmas with Ar X-Ar XIV line emission, in which the degree of ionization was controlled by the magnitude of the current pulse. The characteristics of these plasmas differ from those created by vacuum discharges in the same capillaries and approach those necessary for soft-x-ray amplification in low-Z elements.born digitalarticleseng©1993 American Physical Society.Copyright and other restrictions may apply.
