MICROWAVE PROBING OF IONIZED GAS FLOWS. Technical Note No. 5
Technical Report
·
OSTI ID:4800842
The measurement of free electron densities and collision frequencies in ionized gas flows by a probing transverse microwave beam is described. Interpretation of the observed reflection and transmission coefficients and their phases was developed on the basis of an idealized plane wave --plane slab model, for which typical results are displayed. Application of the device and technique to a specific experiment, the build-up of ionization behind a strong shock in argon, is outlined. Effects of various departures of the microwave radiation patterns and flow configurations from the slab assumptions are discussed and examples evaluated. (auth)
