Neo-Canonical Profiles of the Electron Density and Temperature of the Plasma in the Hot Ion Mode at the Globus-M2 Tokamak

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 Tₑ(ρ ) = const 1pt nₑ(ρ )^1.65 . An analytical model of the density attractor, assuming the dependence of nₑ 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 nₑ(ρ )v(ρ )^1.06 = const . The proposed model makes it possible to calculate the spatial distribution Tₑ(ρ ) and nₑ(ρ ) according to a known magnetic configuration.
