A PROBE FOR ELECTRICAL CONDUCTIVITY MEASUREMENTS IN IONIZED GASES

Abstract

A probe technique for measuring the electrical conductivity in a small region of an ionized flow field is described. The technique involves observing the interaction between an ionized gas and a small perturbing R.F. magnetic field. The probes are basically small coils. Several probes have been dynamically calibrated in a shocktube. A few preliminary measurements were made in the wake of a 4-inch sphere which was subjected to high-speed flight conitions.
