The article presents the results of testing the scenarios of discharge developed and verified using the DINA code on the KTM tokamak during the autumn-winter campaign of 2021. The qualitative difference between the developed scenarios is an increase in the plasma current and discharge duration with a constant breakdown stage at a bypass voltage of 6 V, as well as the presence of a software stage of reducing the plasma current before the discharge is completed. In addition, technological limitations were taken into account in the form of the absence of current reversal in the inductor winding during the discharge. and minimization of current reversal in the control windings in the zone of near-zero currents. The work carried out in 2021 was the next significant step towards bringing the KTM unit to design parameters.
