SPACE-CHARGE WAVES AND PLASMA DIAGNOSTICS

Abstract

The properties of the characteristic modes of propagation on an axially magnetized cylindrical plasma column are reviewed briefly. It is then shown that in some cases these modes can give rise to errors in the measurement of the properties of a plasma by the conventional microwave transmission method of plasma diagnostics, where it has been tacitly assumed that the plasma is very large compared to the wavelength of the diagnostics signal. The specific case of electric vector parallel to the axis of a plasma column is analyzed to illustrate the essential features of the coupling of a diagnostics signal to the space-charge-wave modes.
