Investigations in the vacuum ultraviolet of a steady state nitrogen plasma
investigationsin00beam.pdf (4.171Mb)Abstract
In preparation for studies of shock waves in a collisionless
plasma, a grazing incidence vacuum spectrograph has been used to
study the vacuum ultraviolet spectra of a nitrogen plasma. The
spectra are formed by a concave grating with a 1-meter radius of
curvature and recorded on Kodak SWR (Shortwave-Radiation) Film.
Analysis of the spectra was by comparison with helium and argon
spectra, with intensity information from densitometric measurement
using a Leeds and Northrup recording densitometer. Relative
intensity determination provides an electron temperature evaluation
technique.
