To further stabilize voltage to be applied to a power supply that accelerates an electron beam and a power supply required for oscillation and improve the gyrotron oscillation efficiency, in a gyrotron, while suppressing costs of manufacture and operation of facilities.SOLUTION: A main power supply 51 feeds power to a main voltage circuit 5 for applying a voltage to an electron gun part 2a and a collector part 26. A body power supply 31 feeds power to a body voltage circuit 3 for applying a voltage to a body part 25 and the collector part 26. A body power supply stabilization circuit 33 maintains to a predetermined output voltage an input-output voltage that changes between an electron gun side supply line 51b of the main power supply 51 in the main voltage circuit 5 and a body side supply line 31b of the body power supply 31 in the body voltage circuit 3.SELECTED DRAWING: Figure 1 【課題】ジャイロトロンにおいて、設備の製造コスト及び運用コストを抑えつつ、電子ビームを加速する電源と、発振に必要な電源とに印加する電圧をより安定させることができ、ジャイロトロンの発振効率の向上を図る。【解決手段】主電源５１が電子銃部２ａ及びコレクタ部２６に電圧を印加するメイン電圧回路５に給電するとともに、ボディ電源３１がボディ部２５及びコレクタ部２６に電圧を印加するボディ電圧回路３に給電し、メイン電圧回路５における主電源５１の電子銃側供給ライン５１ｂと、ボディ電圧回路３におけるボディ電源３１のボディ側供給ライン３１ｂと、の間で変動する入出力電圧をボディ電源安定化回路３３が所定の出力電圧に維持する。【選択図】図１
