1. Methods of determining electron concentration and their collision rates by probing plasma with electromagnetic radiation from an external source are known and are being actively pursued [58-64]. If one of these methods is to be applied In real MHD generators, where the ports to the working fluid are limited by the relatively small openings and narrow apertures, it is expedient to probe the working fluid perpendicular to its surface and to make observations along the line of sight. It would be expedient to use methods that provide data on the working fluid of the MHD generator both in a magnetic field and in its absence. In this case, the most suitable technique is measurement of the phase shift and attenuation of plane-polarized electromagnetic waves.
