SCALING PARAMETERS FOR LOW DENSITY FLOWING PLASMAS. PART I. ELECTRON BEAM STUDIES OF THE GAS-SURFACE INTERACTION PROCESS. PART II.

Abstract

Work is reported on measurements in the cryo-pumped plasma tunnel, which extends the capabilities to more rarefied conditions. Work is also reported on electron beam-plasma interactions aimed at developing a new diagnostic technique. Earlier work established the feasibility of using pulsed electron beams to measure molecular velocity distribution functions based on the metastable molecule time-of-flight technique. During the present period, work has proceeded on an intensive quantitative investigation of all aspects of the technique which it is necessary to understand if it is to be used on various gases or in various velocity regimes. Work has also proceeded on an experiment to use this technique to look at the velocities of high energy beam molecules reflected from known surfaces. (Author)
