AN ELECTRON BEAM DEVICE FOR REAL GAS FLOW DIAGNOSTICS

Abstract

An electron beam device suitable for use in low density, nonradiating flows is described. It is shown that in certain ranges of gas density the electron beam can be employed to determine the rotational temperature, vibrational temperature and concentration of molecular nitrogen in a high speed air flow. The theoretical analysis required for interpretation of the data obtained with an electron beam is presented and examples of application of the technique are given. Certain design criteria for electron beam generators are discussed.
