Main experimental work results of obtaining plasma discharge at KTM tokamak are outlined in the paper. Results of initial prebreakdown magnetic field configuration scenario calculations by Plasmaless Tokscen numerical code and results of measuring parameters of selected scenario by diagnostic set of KTM are shown. All KTM electromagnetic system power supplies have been used during experiments on KTM tokamak. However, power supplies of central solenoid and toroidal magnetic field coils have been used only on its half project power, because of incompleteness of commissioning works.

The article presents the calculated variants of current scenarios for the realization of ohmic breakdown of the hydrogen gas in the KTM tokamak. The magnetic configuration of the fields at the time of the breakdown and the main parameters of the breakdown in the vacuum chamber are given, taking into account the basic conditions and limitations for the KTM tokamak. Current scenarios are prepared using the Plasmaless Tokscen calculation code. Based on the calculated estimates of the feasibility of the breakdown, optimal values of the necessary parameters for starting work on the KTM tokamak were selected.

The paper deals with a complex of OHF diagnostics of tokamak KTM, designed to measure the electron density of the plasma. The composition of the OHF diagnostics, their technical features of execution and placement are discussed, and the first experimental results on the measurement of the electron density of the KTM plasma using them are presented. Special attention is paid to the principle of operation of OHF devices and the location of diagnostics on the tokamak.
