Abstract

Gyrotrons at high frequency with high output power are mainly developed for microwave heating and current drive in plasmas for thermonuclear fusion. For the stellarator Wendelstein 7-X now under construction a 10 MW ECRH system is foreseen. A European collaboration has been established to develop and build the 10 gyrotrons each with an output power of I MW for continuous wave operation (30 min). The design parameters of the gyrotron are summarized.
