Determining Plasma Isotopic Composition from the Alfvén Oscillation Frequency in the TUMAN-3M Tokamak
2019
We discuss the possibility of determining the evolution of the isotopic composition of plasma by the frequency of Alfven 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 nH/(nH + nD) and deuterium nD/(nH + nD) 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.
