Study of the soft x-ray emmission from carbon ions in a capillary discharge Rocca, Jorge J. ; Marconi, Mario Carlos ; Tomasel, F. G. "This work was supported by the Department of Energy, Advanced Energy Projects Grant DE-F602-91ER12110 and by the National Science Foundation by Grant ECS 9013372. The work of M. C. Marconi was supported by the Universidad Nacional de Buenos Aires and Consejo Nacional de Investigaciones Cientificas y Tecnicas de la Republica Argentina." The soft x-ray emission from plasma produced in polyacetal and polyethylene capillary discharges excited by current pulses 100 ns full-width half-maximum (FWHM), 50 ns risetime, and peak currents up to 60 kA has been studied. Time-resolved spectra show that intense CVI line emission dominates in the polyethylene discharges, peaking shortly after the maximum of the current and vanishing before the end of the current pulse. Polyacetal capillary spectra are dominated by OVI lines and show weak CVI emission. Plasma density and temperature for the polyethylene discharge were derived from the Stark broadening of CVI Balmer lines and the relative intensities of CVI and CV lines. A short (5 ns FWHM) pulse of energetic beam electrons was detected in coincidence with the onset of the discharge. The results are discussed in relation to the possibility of obtaining soft x-ray amplification by plasma recombination in a capillary discharge plasma column. Colorado State University.
