ICRF system on CFETR

The Chinese Fusion Engineering Testing Reactor (CFETR) is the next device for the Chinese magnetic confinement fusion (MCF) program which aims to bridge the gaps between the fusion experiment ITER and the demonstration reactor DEMO. CFETR will use either the hybrid or the steady-state plasma operating scenario to generate over 1 GW of fusion power. ICRF is a key H&CD system which will play a very important role for CFETR. The ICRF system will deliver 30MW of RF power to the plasma with frequency in the range 40-90MHz using an ITER-Like antenna through located in a mid-plan port. The concept and engineering design of CFETR ICRF system have been carried out and progresses have been made. To establish a solid technical base for a successful construction of CFETR, a national big science facility aiming at developing key technologies and systems for CFETR, called Comprehensive Research Facility for Fusion Technology (CRAFT), has been approved by the Chinese government. The construction of CRAFT has started. This paper reports on the conceptual design of the ICRF system for CFETR; it describes the potential of heating schemes, and describes the design activities of the high-power RF sources, transmission lines and ITER-type antenna. The status of the R&D for key CFETR ICRF system components is presented, and the strategy to test the system in the Comprehensive Research Facility for Fusion Technology (CRAFT) is described.
