Application of polarimetry to test the models of thermonuclear plasma and determination the safety factor profile

Abstract

On the basis of the angle variables technique (AVT) the changes of polarimetry state of the electromagnetic wave passing through the thermonuclear plasma have been analysed. Numerical calculations have been carried out for the typical profiles of the current density flowing through the plasma. Then, for a given current density model the safety factor profile has been designated. All numerical calculations were being performed for plasma parameters that occur in the real reactors.
