MEASUREMENTS OF ANISOTROPIC PLASMAS USING A TURNSTILE MULTIPLE PROBE POLARIMETER,

Abstract

A turnstile multiple probe polarimeter was designed for plasma diagnostics at microwave frequencies. With the polarimeter it is possible to simultaneously measure the amplitude and phase of the space quadrature components of an electromagnetic wave of arbitrary polarization. This technique is thus well-suited for determining the properties of time varying or steady state anisotropic plasma. Measurements were conducted at a frequency of 9.2 Gc on a helium afterglow in a magnetic field using both linearly polarized and circularly polarized incident plane waves. The agreement of these experiments with theory indicate that the multiple probe polarimeter can be a reliable tool for plasma measurements. (Author)
