Abstract :
ITER, the International Thermonuclear Experimental Reactor, proposes to use electron cyclotron technology on an unprecedented scale. ECRF (electron cyclotron range of frequencies) will be used for start-up, heating, noninductive on-and off-axis current drive, and wall conditioning. Advanced gyrotron sources will be needed in order to fulfill the unique requirements imposed by these applications. Consequently, an international R&D program has been undertaken to develop 170 GHz, CW, 1 MW, ~50% efficient tubes. The rationale for the R&D program is presented and design issues relating to the efficient generation, transmission, and delivery to the plasma of over 50 MW of ECRF power are discussed
