Radiation-cooled multistage depressed collector for a microwave tube and microwave tube comprising such a collector

摘要

1. Radiation-cooled multistage depressed collector for a microwave tube, comprising a plurality of electrodes inside a substantially cylindrical vacuum envelope formed of an insulating material, located on the trajectory of the electron beam of the tube and connected to different potentials, characterized in that the electrodes (2) are secured to the vacuum envelope (1) through metallic fixtures (3).
