The application of dynamic mass spectrometers for investigations in the field of thermonuclear synthesis

Ioffe Institute, ul. Polytekhnicheskaya 26, St. Petersburg, 194021, Russian Federation

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.
