Abstract
The possibilities are considered of using the Thomson scattering diagnostics of core and edge plasmas in the tokamak with reactor technologies, which is under design. The problems are described that can be solved using the Thomson scattering diagnostics, including the possibility of controlling the plasma current profile. Technical requirements for the diagnostics are formulated. The possibilities are analyzed of its arrangement in the tokamak vacuum chamber. The accuracies are estimated of measuring the electron temperature and density of the plasma created in the tokamak. Particular attention is paid to ensuring the operability of the proposed diagnostics in the reactor regime of the tokamak operation.

Funding
The formulation of the problems that can be solved with the help of the TS diagnostics, as well as formulation of the technical requirements for the TR system (Sections 1 and 2), were supported by the Ministry of Education and Science of the Russian Federation under the State Contract no. 0040-2019-0023. The working out of the schemes for placing the diagnostics at the tokamak, as well as the analysis of the expected measurement accuracy (Sections 3, 4, and 5), were supported by the Ministry of Education and Science of the Russian Federation under the State Contract no. 0034-2019-0001.
