Abstract This article presents estimates of the operating region of the KTM tokamak in terms of plasma density and current for ohmic regimes on the basis of machine design parameters. The discharge parameters obtained in the experiments in 2021 are plotted on the diagram (ne, Ip). The increase in operating values of plasma current and achievement of boundary values of stability factor q ~ 4 are mentioned. It has been demonstrated that progressing into the region of higher plasma currents in the implemented density range leads to achievement of the limit in development of beams of accelerated electrons. Accordingly, the increase in operating plasma density is one of the aims of the next experimental campaign at the KTM tokamak.
