X-ray spectroscopy at "S-300" facility

Abstract

X-ray spectroscopy is one of the most informative diagnostics used on the "S-300" facility (3-4 MA, 600 keV, 100 ns). A specially designed crystal spectrograph permits one to get time-integrated [H]- and [He]-like ion spectra with two-dimensional spatial resolution in each experiment run. Computer processing of the spectra gives electron and ion temperature, hot plasma density, energy radiated in separate lines and geometry shape of the radiation source. X-ray spectroscopy methods and some results from the light liner and Z-pinch experiments are reported in this paper.
