| Research Abstract |
Development of collective Thomson scattering(CTS) diagnostics for measurement of ion temperature of fusion plasmas is needed. A development study of high power sub terahertz gyrotron applicable to CTS has been carried out. Second harmonic oscillation was adopted to avoid technological limitation of a superconducting magnet and the design method of state of the art was applied. As a result, highest power of 83 kW at 0. 389 THz was demonstrated. Moreover, a practicable internal mode convertor was designed and fabricated.
