DETERMINATION OF CHEMICAL SPECIES PREVALENT IN A PLASMA JET.

Abstract

The program demonstrated the feasibility of using a Bendix Time-of-Flight Mass Spectrometer to study plasmas existing at atmospheric pressure. A Time-of Flight Mass Spectrom eter and an optical spectrograph were modified to enable analyses of molecular, atomic, and ionic species obtained in similar and related plasmas at atmospheric pressure. Stabilized electric arcs of both argon and simulated air were analyzed in an attempt to understand the chemical, thermodynamic, and heat transfer processes occuring therein. These experimental investigations produced both qualitative and quantitative data, but the optical equipment produced little useful information. A Bendix Time-of Flight Mass Spectrometer was used for plasma analyses; necessary modifications to this instrument to adapt it to program needs were completed during the early stages of the program. Several sampling probes were designed, built, and tested. One of these, a supersonic probe design, was successfully used to perform plasma analyses at atmospheric pressure. (Author)
