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.
