Time and space resolved vacuum-ultraviolet spectroscopy of an argon gas-puff Z pinch

Abstract

Time and radially resolved vacuum‐ultraviolet spectra from an argon gas‐puff Z pinch have been obtained using a grazing incidence spectrometer with gated microchannel plates curved to the Rowland circle. Most of the 50–300‐Å radiation is emitted from a dense core (r≊0.4 mm, n_e≳10¹⁹ cm⁻³, T_e≊150 eV) which forms when the plasma assembles on the axis.
