Abstract :
A high power 300 GHz band pulse gyrotron has been designed and fabricated based the design concept for stable and single mode oscillation that has been experimentally verified with a prototype gyrotron. It will be practically use in the collective Thomson scattering (CTS) diagnostics in the Large Helical Device (LHD). The oscillation frequency is 303 GHz and the design calculation predicts stable oscillation of over 300 kW power at fundamental harmonic resonance.
