Siusko Y. Application of microwave refraction for diagnosis of inhomogeneous plasma

The methods of plasma diagnostics based on refraction have been developed in the dissertation work, namely: the measurement of microwave phase shift at inclined plasma probing with horn antennas fixed in space, the method of determination of azimuthal inhomogeneities of rotating plasma. Inclined probing (in the case of horn antennas fixed in space) has been proposed to implement using the peripheral part of the horn antenna radiation for the first time. Measurement of the phase shift of waves in inclined probing and the method of determining the azimuthal inhomogeneities of rotating plasma can be used as the methods for diagnosing plasma, which make it possible to obtain information about peripheral plasma and determine azimuthal plasma inhomogeneities respectively. These methods can be used both in the study of laboratory plasma and in the devices of controlled thermonuclear fusion.
