TL;DR: In this paper, an X-ray diagnostic system for determining the metal vapor concentration in a high-current pulsed discharge in high and ultrahigh-pressure gas based on a pulsed Xray source in a spectral region of 20-50 keV was designed.
Abstract: An X-ray diagnostic system for determining the metal vapor concentration in a high-current pulsed discharge in a high- and ultrahigh-pressure gas based on a pulsed X-ray source in a spectral region of 20–50 keV and an X-ray CCD camera has been designed. Two nanosecond generators with durations of high-voltage pulses of 10–20 and 50 ns and new through-target-type X-ray tubes were used. Experiments on the diagnostics of a high-current discharge in an axially symmetric electrode system have been performed at dJ/dt = 109–1011 A/s and discharge currents <1 MA. The data on the spatial distribution of metal vapors injected from the electrodes as a result of erosion are obtained.
