Abstract

The 2-MW ECRH mm-wave system has to operate under various vacuum conditions. The aim of the mm-wave system to be installed in the ITER upper-port system is to inject electron cyclotron waves (ECW) in the ITER plasma in order to stabilize neoclassical tearing modes (NTM). The design analyses have demonstrated the feasibility of the remote steering approach in the ITER environment. In order to exploit the capability of ECW for localised heating and current drive over a range of plasma radii in ITER, the ECH and CD upper port launcher must have a beam steering capability.
