RADIATIVE PROPERTIES OF HOT DENSE X-PINCH

A high luminosity spectrometer with a spherically bent mica crystal ha s been used to obtain H- and He-like spectra of Al and Si ions in X-pi nch plasma with high spectral (lambda/DELTAlambda approximately 3000) and spatial (approximately 30 mum) resolution. The electron density (u p to 2.10(24) cm-3) and the temperature (up to 950 eV) in the ''hot po int'' were measured by means of X-ray spectroscopy methods. The estima tes show, that the emission of K-line radiation can be up to 1 J, the power being 10(9) W). The total energy emitted in the spectral region 5-100 angstrom is about 1 kJ.
