Abstract: It is shown that the radial profile of the electron temperature in the Globus-M2 spherical tokamak is related to the radial profile of the electron density by a power law ${{T}_{e}}(\rho ) = {\text{const}}{\kern 1pt} {{n}_{e}}{{(\rho )}^{{1.65}}}$. An analytical model of the density attractor, assuming the dependence of ${{n}_{e}}$ on the specific poloidal volume $v$, previously tested on the TCV and JET tokamaks with a large aspect ratio, holds on the spherical tokamak, and the approximation of 162 experimental profiles has resulted in ${{n}_{e}}(\rho ){v}{{(\rho )}^{{1.06}}} = {\text{const}}$. The proposed model makes it possible to calculate the spatial distribution ${{T}_{e}}(\rho )$ and ${{n}_{e}}(\rho )$ according to a known magnetic configuration.
