Estimation of the KTM tokamak working area in terms of the plasma density and plasma current is presented for ohmic discharges basing on the design parameters of the machine. The (ne, Ip) diagram contains the discharges obtained in the autumn campaign of 2021. Increase of the operating values of the plasma current and achieving the value of the edge safety factor q ~ 4 are marked. It has been shown that the transition to the region of higher plasma currents in the realized density range leads to the approaching the limit on the development of the beams of runaway electrons. Accordingly, increase of the plasma density operating values is one of the objectives of the next experimental campaign on the KTM tokamak.
