Paper Abstract

At the University of Massachusetts we are applying the technique of time-resolved FTS to the study of the negative glow IR emission spectrum of a low pressure glow discharge. For a given pressure and peak excitation current, we have found that the infrared spectral Features of N2 emission vary markedly as a function of both pulse repetition rate and pulse width. In order to observe this behavior without erroneous spectral artifacts, real-time signal processing has been incorporated into the experiment, with special emphasis on D.C. restoration. The relaxation phenomena inherent in our source, coupled with low S/N ratios and high duty cycle, require unique signal processing that is facilitated by computerized techniques.
