Abstract

A pulsed image intensifying tube is described for use as a shutter in a snapshot spectroscopic investigation of a shock-heated hydrogen plasma. The shutter was placed at the image plane of a spectrograph to obtain snapshot photographs of the H_β line profile and the underlying hydrogen continuum. Electron density measurements of 0.8−2 × 10¹⁷ cm⁻³ were obtained from the width of the Stark broadened H_β line. Plasma temperatures in the range 2 eV to 6 eV were obtained from the H_β line to hydrogen continuum ratio. An independent and simultaneous electron density measurement was obtained photoelectrically from the absolute specific intensity of the hydrogen continuum as a check on the image intensifying shutter measurements. This agreement was within the 10% experimental error. Time-resolved photographs of the plasma structure were also taken with this shutter.
