Experimental Studies of Photoionization Processes in Air
Abstract
An experimental study is described whose objectives is to assess the role of NO in the nonequilibrium vacuum ultraviolet (VUV) radiation from shockheated air. The experiment utilizes a splitter-plate shock tube technique wherein the VUV radiation behind a reflected shock is used as a light source to measure the absorption by gases processed only by the incident shock wave. In addition, nonequilibrium radiation profiles behind strong incident shock waves are also measured to aid in the identification of the relevant excitation processes. The report describes the apparatus, discusses the results of calculations needed to establish testing parameters, and presents the experimental measurements to date. (Author)
