This review discusses the design, analytical characteristics and some applications of two types of dynamic mass spectrometers that have been developed at the A.F. Ioffe Physical-Technical Institute, Russian Academy of Sciences: magnetic resonance mass spectrometer (MRMS) and time-of-flight mass spectrometer (TOFMS), the latter of which the authors named mass reflectron. With the aid of MRMS it was possible to measure the half-life of tritium, which is a fusion fuel candidate; and to start investigating how deuterium plasma interacts with the structural materials of the spherical tokamak Globus-M. The research done shows that mass reflectrons can be used successfully in the analysis of tritium-containing fusion fuel gas mixtures.
