MEASUREMENT OF ELECTRICAL CONDUCTIVITY IN THE WAKE NECK.
Abstract
Use of a RF conductivity bridge to determine the electrical conductivity of the plasma in the wake neck is examined. The plasma to be measured is within the measurement capability of the instrument. Curves of electron density as a function of static enthalpy and pressure are presented. Electrical conductivity as a function of enthalpy with pressure as a parameter is calculated, and the results are given in graphical form. Calibration constants for the bridge are determined by use of computer solutions to equations discussed in the text. Aspects of instrument application such as minimum measurable, linear output range, skin depth, cyclotron frequency, tensor, and phase angle of the eddy currents, are discussed. The results of the feasibility study are summarized. (Author)
