SUMMARY OF TECHNOLOGY FOR ELECTRON CYCLOTRON HEATING AND CURRENT DRIVE

The progress on electron cyclotron heating and current drive (EC H&CD) presented in the EC-15 workshop is summarized. Significant progress has been made on gyrotron development. In particular, following a long term R&D effort, gyrotron performance has now exceeded the ITER criteria. Progress of R&D and the design of ITER launchers and transmission lines were presented, which gives a clear prospect for EC H&CD system availability on the first day of operations. In parallel, many efforts devoted to innovation and upgrading of EC H&CD systems on worldwide fusion devices were reported.
