MICROWAVE MEASUREMENTS OF FINITE PLASMAS,

Abstract

Investigations are described which were designed to tesuthe idity of various theoretical treatments of plasma properties and to assess the accuracy of various microwave systems for determining the properties of plasmas which are finite in extent using free-space microwave, techniques. Theoretical results are obtained for pr iction of plasma effects. Measurements on various experimental geometries demonstrate the influence of the dielectric boundaries of the plasma container, thef ffect of multiple reflections within the measurement sys m, zdu he precautions which must be exercised both in the measurement and interpretation of the results. Measurements of sma properties using a number of diffrowave arrangements are assessed and the limitations of the various systems shown. Finally, free-space microwave determination of the properties of a plasma generated in Helium and in Argon are presented. (Author)
