Next target in the JAEA is development of advanced gyrotron for ITER such as high power repetitive operation, high frequency power modulation and dual frequencies. In repetitive operation, 400 s pulse operation was 10 times with pulse interval of 30 min was demonstrated. In high frequency power modulation, 300Hz-5min full modulation and 5kHz-10s RF modulation were demonstrated. In parallel, higher order mode gyrotron with TE31,11 have been manufactured and high power test was just started. In preliminary result, dual frequencies of 170 GHz with TE31,11 and 137 GHz with TE 25, 9 and high power output more than 1 MW were obtained in the short pulse operation.
