Advantages of using the extraordinary wave (X-wave) with a frequency below the electron cyclotron frequency for the diagnostics of a magnetoactive plasma are analyzed with regard for the experimental conditions on a U-3M torsatron. The refraction of microwaves at the oblique plasma probing is studied taking the poloidal component of a magnetic field into consideration. The Doppler shift of an X-wave reflected from the moving plasma layer is found to exceed that of an ordinary wave (O-wave).</p> ER -
