Experimental investigation of emission from a low-temperature air plasma in the vacuum ultraviolet spectral region
Abstract
A method for measuring total vacuum ultraviolet plasma emission is presented, and measurements by this technique of an air plasma in a shock tube are reported. The experimental method is based on the luminescence of a luminophor (sodium salicylate) irradiated by UV radiation and emitting in the visible. Vacuum UV fluxes emitted by plasmas behind incident and reflected shock waves in a shock tube at temperatures between 8200 and 11,500 K and 17,000 and 19,000 K determined by the apparatus described are found to agree with calculated values to within experimental error.
