Investigations in the vacuum ultraviolet using a grazing incidence spectrograph.
investigationsin00kauf.pdf (2.303Mb)Abstract
A grazing incidence vacuum spectrograph has been used for
studies on high temperature plasmas and to investigate the Tungsten
spectra produced by a vacuum spark source. The spectrograph
uses a concave grating which has a 1-meter radius of curvature
and 6DD grooves per mm. Incident light strikes the grating at an
angle of 8.15 , and the diffracted light is collected on a film
strip (15-inches long, 35 mm SDR film) which is held along the
Rowland circle.
Design and details of construction of the spectrograph and
the vacuum spark source are presented. A total of kl new Tungsten
lines were identified from the vacuum spark source using
Aluminum and Tungsten electrodes.
