All rights reserved.Electron cyclotron heating is one of the methods of additional plasma heating and noninductive current drive in T-15MD tokamak. One to eight gyrotrons with a total power up to 7 MW will be used. The frequency of the microwave used depends on the parameters of the experimental scenarios in which the heating will be used and on the physical tasks for which it is intended. This article provides justifica-tion for the choice of the gyrotronsi frequency f1 ° 82.6 GHz for the start-up phase and for the first plasma experiments, and considers the possibility of using this frequency at the stage of full-scale experiments. In order to provide flexibility of the .-15MD ECRH system, it is proposed to consider the possibility of the development of a gyrotron complex based on two-frequency gyrotrons with f1 ~ 82.6 GHz and f2 in the range of ~ 102-X110 GHz.
