Abstract
The divergence of the C VI 182-Å lasing line generated in a rapidly recombining, magnetically confined plasma column was measured with soft—x-ray spectrometers equipped with multichannel detectors. In addition to measurements of the relative divergence, an absolute divergence of ∼9 mrad at a magnetic field of 20 kG and ∼5 mrad at a magnetic field of 35 or 50 kG was obtained by a direct scan of the 182-Å axial radiation. Based on these data a peak 182-Å power of ∼100 kW is obtained. Calculations of the spatial distribution of gain in the plasma were in very good agreement with the experimental data.Keywords
