INVESTIGATIONS IN THE VACUUM ULTRAVIOLET USING A GRAZING INCIDENCE SPECTROGRAPH.
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 600 grooves per mm. Incident light strikes the grating at an angle of 81.5 degrees, and the diffracted light is collected on a film strip (15-inches long, 35 mm SWR 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 47 new Tungsten lines were identified from the vacuum spark source using Aluminum and Tungsten electrodes. (Author)
