It will be used for many experimental purposes such as localized electron heating and current drive, stabilization of instabilities, plasma start-up assist and wall cleaning. The maximum heating power of 7 MW for the pulse duration of 100 s will be provided by means of 9 units of gyrotrons (1 MW each), 9 units of waveguide transmission lines (transmission efficiency of 75 – 80%) and 4 units of launchers. The gyrotron is featured by a capability of operations at three frequencies of 110 GHz, 138 GHz (1 MW/100 s) and 82 GHz (1 MW/1s) [1]. Toward the successful start of plasma experiments of JT-60SA, which is scheduled in 2020, R&D and preparation of the ECH/CD system components are progressing. In this presentation, R&D results on the ECH/CD launcher and the status on the preparation of the ECH/CD system components such as transmission line, control and power supply are reported., Japan-Korea Workshop on “Physics and Technology of Heating and Current Drive”}, title = {R&D and preparation of ECH/CD system for JT-60SA}, year = {2018} }
