Abstract:

A probe technique for measuring the electrical conductivity in a small region of an ionized flow field is described. The technique involves the observation of the interaction between an ionized gas and a perturbing R.F. magnetic field of low strength. The probes are basically small coils mounted on ferrite supports and are presently undergoing dynamic calibration in a shocktube specially designed for that purpose. The shocktube is instrumented with a 70 KMC microwave interferometer which yields direct electron density information as a comparison parameter. Author
