Abstract
This paper presents the results of the first experimental tests of the ion cyclotron radio-frequency (RF) plasma heating system of the KTM tokamak with an equivalent plasma load. Measurements of the operating parameters of the RF generator and the antenna-feeder system were carried out under conditions approximating plasma operation. The generator circuits were tuned and matched to the load, and the generation characteristics as well as the conditions for stable RF power transmission to the load were investigated. Stable operating regimes of the system and the conditions ensuring stable RF power generation were determined. The test results confirm the functionality of the main components of the RF heating system and demonstrate the possibility of further testing with plasma in the KTM tokamak.
