Outline of Final Research Achievements |
Output power of 234 kW was obtained with a 294 GHz prototype gyrotron in fiscal year 2013. Further higher power of 246 kW was demonstrated and the design concept for high power sub THz gyrotron was verified in fiscal year 2014. Then, a 303 GHz practical gyrotron was designed and fabricated. Oscillation test in fiscal year 2015 resulted in a maximum power higher than 320 kW and an efficiency higher than 30%. In fiscal year 2016, the pulse width was expanded up to 80 microsecond. Frequency variation during the oscillation pulse was measured and the frequency variation less than 10 MHz was confirmed. In addition, no-parasitic mode oscillation including turn-on and turn-off phases was realized. We have successfully developed a sub THz gyrotron applicable to collective Thomson scattering diagnostics.
