Therefore, it has the advantage of being able to use a single method of electron beam and high frequency circuit to a large extent, and the efficiency is relatively high. Conventional - A commonly known rotary rotor has a configuration as schematically shown in FIG. 2.

１ 。(Problems to be Solved by the Invention) A gyrotron having such a structure has an output window arranged axially symmetrically so that the electron beam can be directly seen through. Therefore, most of the electron beam is transmitted to the collector section "C"
Even if it is captured, it is unavoidable that the J3 section will collide with the output window.The electron beam that collides with the output window may damage the ceramic plate that passes through the window material. To solve this problem, there is a configuration in which the output window is electrically insulated from the collector section and a negative potential is applied to it.
た、特開昭５９４’１９６４８号公報に開示されるよう
に）コレクタ部の外側に電磁コイルを配置して軸に直交

にする提案もある。There is also a proposal (as disclosed in Japanese Patent Laid-Open No. 594'19648) to place an electromagnetic coil outside the collector section and apply a magnetic field perpendicular to the axis to bend the electrons and trap them in the collector section. .
しかしながら、前者の場合は出力窓部の電位を相当低く

出力窓部との信頼性の高い電気的絶縁構造が必要となる
。−方後者の場合は、余分の電磁コイルおよびその電源

となって温度の不均衡が生じてしまう。However, in the former case, a sufficient effect cannot be obtained unless the potential of the output window section is set to a considerably low level, and a highly reliable electrical insulation structure between the collector section and the output window section is required. - In the latter case, an extra electromagnetic coil and its power source are required, and the inflow of electrons into the collector portion becomes asymmetrical, resulting in temperature imbalance.

電子ビームの衝撃現象を抑制して信頼性の高いジャイロ
トロンを提供するものである。The present invention provides a highly reliable gyrotron that eliminates the above-mentioned disadvantages and suppresses the impact phenomenon of electron beams on the horn window.

。[Structure of the Invention] (Means for Solving the Problems) The present invention provides a circular guide between a collector section made of a circular waveguide and an output window section so that the output window cannot be seen from the electron gun assembly. This is a gyrotron that uses a wave tube bend.

で折曲げられている。As shown in FIG. 1, a circular waveguide bend 20 having the same cross-sectional shape is interposed between a collector section made of a circular waveguide and an output window section, and is continuously integrally constructed. This waveguide bend 20 is located at a position where the ceramic plate of the output window 17 cannot be directly seen from the electron beam generating part of the electron gun assembly 11, and at a position sufficiently shifted from the electron beam axis, that is, the main tube axis passing through the resonant cavity 14. It is bent into a size and shape that gives it.

There is almost no shock caused by the electron beam. Also, there is no need for an extra magnetic field device or power supply to apply an orthogonal magnetic field, and highly reliable operation can be obtained.
