Claims

[Claims for Utility Model Registration] (1) A microwave tube in which a plurality of plate collector electrodes each having an electron collection surface formed with an opening for electron passage are arranged at intervals in the direction of electron flow. A multi-stage collector for a microwave tube, characterized in that the electron-collecting surface is provided with a rib that protrudes in the thickness direction of the plate material and extends along the surface of the electron-collecting surface. (2) In a multi-stage collector for a microwave tube in which a plurality of plate collector electrodes each having an electron collection surface formed with an opening for electron passage are arranged at intervals in the electron flow direction, the electron collection 1. A multi-stage collector for a microwave tube, characterized in that a converging surface has a continuous bent piece bent from the opening edge in the circumferential direction of the opening at the opening edge of the collecting surface.
