Abstract: We discuss the possibility of determining the evolution of the isotopic composition of plasma by the frequency of Alfvén oscillations in ohmic discharges in the compact TUMAN-3M tokamak with pulsed deuterium puffing into a hydrogen plasma and hydrogen puffing into a deuterium plasma. The isotopic ratios, i.e., relative concentrations of hydrogen $n_{\mathrm{H}}/(n_{\mathrm{H}}+n_{\mathrm{D}})$ and deuterium $n_{\mathrm{D}}/(n_{\mathrm{H}}+n_{\mathrm{D}})$ in the mixed hydrogen–deuterium plasma obtained by this method are in qualitative agreement with the results of spectroscopic measurements and neutral particle analysis data.

Keywords: tokamak, Alfvén oscillations, plasma isotope composition.
