Abstract

With the view of developing a suitable medium for soft X-ray lasing action in the strongly recombining phase of a CO₂ laser produced plasma, we have concentrated on studying the UV and soft X-ray emissions of hydrogenic carbon (CVI) and the Li-like sequence CIV, OVI, FVII, and NeVIII. These absolutely calibrated spectra, both time integrated and time resolved, have been measured perpendicular and parallel to the plasma column. Plasma density and temperature have been estimated from this data using Stark broadening, recombination continua and dielectronic satellites. Satellites have also been used to estimate self-absorption in lines of interest, especially CVI Lyman α.
