• 一般注記: High-power sub-terahertz pulse gyrotrons are under development in FIR FU for application to collective Thomson scattering (CTS) measurement on fusion plasmas, especially on high-density plasmas such as those produced in LHD. Recently, we achieved a new power record of 62 kW at approximately 388 GHz with secondharmonic (SH) oscillation. Following this result, we modified the electron gun of the gyrotron to couple the electron beam more strongly to another oscillation mode that has a peak coupling coefficient two times as large as that of the 62 kWmode. Oscillation tests with the new mode attained higher power of 83 kWat about 389 GHz. These results constitute new second-harmonic-oscillation power records for sub-terahertz gyrotrons.
