Abstract
Disclosed is a multistage electron collector for electron tubes. This collector comprises an imperviously sealed envelope subjected to vacuum with an input wall and a back. Within, there is a succession of electrodes and dielectric spacers. Two successive electrodes are insulated by a spacer of a first type in contact with the two electrodes and having no contact with the envelope. A spacer of a second type is in contact firstly with the electrode closest to the back and secondly with the back. Application to electron tubes, especially millimeter travelling wave tubes.
Claims16
A multistage electron collector for electron tubes, said collector comprising a vacuum-tight envelope with an input wall of said electrons and a back that are electrically conductive, this envelope containing, in the vacuum, a succession of electrodes and dielectric spacers, two successive electrodes being insulated by a spacer of a first type in contact with the two electrodes and having no contact with the envelope, a spacer of a second type being in contact firstly with the electrode closest to the back and secondly with the back, wherein the electrode closest to the input wall is separated, only by the vacuum from the input wall, and wherein the envelope comprises, between the input wall and the back, a part used as a thermal brake.
