Abstract:

The initial phase of a microwave diagnostics program involving seeded rocket exhaust gases is presented. The theory of the microwave determination of electron density and collision frequency is discussed as it applies to the temperature and density regimes of both thermo nuclear and chemically-produced plasmas. The procedure used to predict the electron density in an equilibrium seeded rocket exhaust gas is outlined, as well as a possible method for temperature measurement using microwave radiation. The experimental apparatus and procedure are described, and the results of ten measurements of electron density are compared with predicted values. The improvements in experimental equip ment and technique planned for future investigations are discussed.
