Abstract

The diagnostic complex of the Globus-M2 spherical tokamak (R = 36 cm, a = 24 cm), the onlyoperating tokamak in Russia with a divertor plasma configuration, which operates in the range of subthermonucleartemperatures (Te to 1.6 keV, Ti to 4.5 keV) and densities (ne to 2 × 1020 m–3), is described. The Globus-M2 tokamak is the unique scientific facility, which is a part of the Federal Center for Collective Use ofthe Ioffe Institute, Russian Academy of Sciences “Materials Science and Diagnostics in Advanced Technologies.”This allows third parties to perform their research using it. The work contains a list of all diagnosticscurrently available on the tokamak. The description of the diagnostics is structured in such a way that thereader gets an idea of their capabilities for measuring plasma parameters with an emphasis on the limits andaccuracy of the measured values, and also spatial and time resolution. At the same time, many technicaldetails are omitted in order to save space; references are given to papers with a more detailed description ofindividual diagnostics.
