Radiative properties of hot dense X-pinch

Abstract

A high luminosity spectrometer with a spherically bent mica crystal has been used to obtain H- and He-like spectra of Al and Si ions in X-pinch plasma with high spectral (λ/Δλ ∼ 3000) and spatial (∼ 30 μm) resolution. The electron density (up to 2.10 24 cm -3) and the temperature (up to 950 eV) in the “hot point” were measured by means of X-ray spectroscopy methods. The estimates 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 Å is about 1 kJ.
