All rights reserved.Electron cyclotron radiation (ECR) in tokamak-reactors, due to high electron temperature and high magnetic field, is expected to play a significant important role in the local electron energy balance and will also be a source of thermal and electromagnetic loads on the in-vessel components and diagnostics. This is especially important for diagnostics using millimeter waves, namely the reflectometry from the sides of the strong and weak magnetic field, reflectometry of the plasma position, as well as collective Thomson scattering, since the transmission lines of these diagnostics allow the transport of EC waves emerging from the plasma and even additional measurements of their spectrum. The paper presents an algorithm for calculating the spectral intensity of EC radiation emerging from the plasma to the first wall for typical conditions of a tokamak-reactor. To illustrate the algorithm, the calculations for typical scenarios of ITER and DEMO tokamaks are presented. The possible effect of this radiation on the in-vessel components and diagnostics of the tokamak-reactor is briefly discussed.
