Abstract (in Japanese) (See Japanese page) 
(in English) Sub-millimeter wave source is needed to enhance the sensitivity of nuclear magnetic resonance (NMR) spectroscopy for complex proteins structure analysis. This method is dynamic nuclear polarization (DNP). The DNP needs irradiation of sub-millimeter wave with the power of several Watt at optimal frequency. Therefore, continuous frequency tunable gyrotrons are required to obtain maximum enhancement. We developed gyrotrons having boardband frequency tunability using a long cavity. The tunable bandwidth was about 1.6 GHz including optimal frequency .
