We estimate the parameters of a Cu plasma generated by an X-pinch by comparing experimentally measured x-rays with synthetic data. A filtered absolute extreme ultraviolet diode array is used to measure time-resolved x-ray spectra with a spectral reso

This paper deals with a newly developed resistive magnetohydrodynamic code, STHENO, for X-pinch analyses on 3D (x, y, z) and 2D (r, z) geometry. The single-fluid two-temperature model is adopted by assuming collisional plasmas. The thermodynamic para

This article presents time-resolved analysis of SF6 arc plasma generated in a laboratory-scale model chamber prepared for studying the characteristics of a circuit breaker. During the arc discharge, the optical emission spectra are measured by a high

This paper presents the electrical conductivity data of copper along the gas branch of the binodal curve in the warm dense matter (WDM) regime as a function of mass density and temperature. All data are obtained using the underwater wire explosion te

We develop a filtered absolute extreme ultraviolet (AXUV) diode array to measure the time evolution of the soft x-ray spectrum in the energy range of 1-10 keV. AXUV-HS5, the detector, has a fast rise time of 0.7 ns, a wide energy detection range, and

Having a sub-ns response time and not requiring physical contacts to the measurement points, a voltage measurement system based on the Pockels electro-optic effect, referred to as a PE (Pockels effect)-based voltmeter, is widely used for pulsed high
