Status of the ITER electron cyclotron H&CD system

This paper presents the status of the design and the integration of the 20 MW EC H&CD system under development for the ITER Tokamak. Progress includes agreement on the first set of procurement arrangements (EC Transmission Line and the RF building housing both IC and EC systems), advancing the design of all components to either the conceptual or preliminary design stage, optimization of gyrotrons performances and finalization of launchers design.
