Abstract:
In this Letter, results of measurements of radiation losses Prad and effective ion charge $Z_\mathbf{eff}$ in the conditions of magnetic field up to 0.7 T and plasma current up to 300 kA for a wide range of electron density first obtained on the Globus-M2 tokamak are presented. The analysis of the results shows the decrease in the radiation losses share of the input power on the Globus-M2 tokamak as compared with the same parameter for the Globus-M facility. A large dip at the center of the $P_\mathbf{rad}$ power profiles is revealed. A decrease in the $Z_\mathbf{eff}$ values is observed with an increase in electron density.
Keywords:
