Abstract: An array of ten built-in divertor probes was installed on the lower dome of the Globus-M spherical tokamak. It was used to measure the profiles of the floating potential, electron temperature, ion saturation current, and heat flux density to the divertor. It is demonstrated that there is a sharp change in the floating potentials of the probes located near the outer separatrix leg at the development of the peripheral instability.
Keywords: tokamak, divertor, scrape-off layer, Langmuir probes.

The development of the array of divertor Langmuir probes for studying the near-wall plasma was supported by a state assignment of the Ministry of Science and Higher Education of the Russian Federation. The experiments were carried out on the unique Spherical Globus-M scientific tokamak facility, which is a part of the Federal Center for Collective Use of the Ioffe Physical Technical Institute, Russian Academy of Sciences, Materials Science and Diagnostics in Advanced Technologies, unique project identifier RFMEFI62119X0021. Numerical simulation was supported by the Ministry of Science and Higher Education of the Russian Federation, project no. 0784-2020-0020.
