Radio frequency heating systems are essential for nuclear fusion research to heat the plasma or drive a current by accelerating electrons or ions confined magnetically. As for the electron cyclotron heating system, a go-ahead method among them, development shows steady progress. Especially the performances of electron tube “gyrotron” which generates a megawatt of radiofrequency power, have already meet the requirement of ITER and JT-60SA, leading the world. The procurement of the electron cyclotron heating system has already been started to these tokamaks.
