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.

Techniques and benefits of shaping the pulses of binary sequences with application to spread spectrum radio communications.
(Monterey, California. Naval Postgraduate School, 1979-03);This research is concerned with binary sequences. Such two-level voltage waveforms are used in some types of spread spectrum systems. Of interest in this work is the effect of shaping the normally rectangular pulses of ... -
