We discuss the development of high-resolution plasma imaging and spectroscopy diagnostics for the soft X-ray and ultraviolet energy ranges developed and used on 100-500 kA pulsed power facilities. Requiring just a few people to run and modest infrast

We have measured the time-dependent radial velocity distributions of singly to five times ionized ions in an imploding plasma shell by observing the spectral shapes and intensities of emission lines in various directions. An ionization wave propagati

Thorough analysis of experimental data (the authors' own as well as those from the literature) on alkali halides and their mixtures with a view to application of a generalized Lindemann criterion for melting is presented. The result of a fitting proc

We describe the investigations of the plasma behavior in three pulsed‐power systems: a magnetically insulated ion diode, and plasma opening switch, and a gas‐puffed Z pinch. Recently developed spectroscopic diagnostic techniques allow for measure

Experimental investigations of the ion density and flow as a function of time and space in z‐pinch plasmas are of key importance for improving the understanding of z‐pinch dynamics. For such studies, measurements of emission‐line shapes can be

The time-dependent radial distribution of the electron temperature in a $0.6\phantom{\rule{0.3em}{0ex}}\ensuremath{\mu}\mathrm{s}$, $220\text{\ensuremath{-}}\mathrm{kA}$ gas-puff $z$-pinch plasma is studied using spatially-resolved observations of li

Semiconductor detectors can provide measurements of the X-ray emission spectra from Z-pinch plasmas with spectral, time and spatial resolution simultaneously. PIN detectors working in the current regime (up to 1 A), fast enough (1 nsec rise time), an
