Abstract

The injection complex that heats plasma of Globus-M2 spherical tokamak consists of two injectors
which supply high-energy beams of hydrogen (deuterium) atoms into the device’s plasma. Injectors are
autonomous and allow for preparing and setting up the device and measuring the parameters of the atomic
beam independently of the other injector and of the tokamak. The authors provide detailed analysis of each
injector’s configuration, substantiate their selection of the experiment layout for introducing beams into the
tokamak plasma, set forth characteristics of both injectors’ atomic beams injected into the tokamak plasma,
and discuss the results of experiments on additional heating of Globus-M2 tokamak plasma obtained by
injecting two atomic beams.
