The study consists of a series of experiments in plasma physics to glean information about the time history of the initiation of a glow discharge in a low pressure gas. General characteristics of a specific glow lamp containing an admixture of mercury vapor and argon were determined. Subsequent experiments were performed spectrally by use of spectroscope, photomultiplier and image converter methods, to evaluate the conditions of the plasma from initial breakdown through the initiation of the first striations. A novel and generally useful method of time resolved, spectrally resolved, absorption measurement is demonstrated with application to the present investigation. Author
