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_H/(n_H + n_D) and deuterium n_D/(n_H + n_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.
