Abstract: The results of experiments on determining the polarization of two types of Alfvеn oscillations observed with magnetic probes in the TUMAN-3M tokamak are presented. The difference in the polarization of short and long bursts of Alfvеn oscillations, arising both in ohmic regime and during neutral beam injection, is found. The role of high-energy electrons in the excitation of Alfvеn oscillations is discussed.

Keywords: high-temperature plasma, tokamak, Alfvе́n oscillations, polarization, suprathermal electrons.
