X-ray spectroscopic characterization of hot spots in neon Z-pinch

Hot spots created in neon gas-puff Z-pinch were studied by precise spectroscopic methods. The macroscopic plasma parameters were found using the contour method and independently confirmed by a detailed comparison of the measured and synthetic spectra. Two groups of hot spots with substantially different electron densities and temperatures were observed, their parameters are discussed with respect to possible photopumping experiments.
