High power electron tube - has discontinuous cathodic emitter, with anode and two control electrodes

摘要

An electron tube of high power in vacuum has a cathodic emitter with a discontinuous surface, one anode and an electrode. The cathode is located between the anode and the electrode which enables the tube to be controlled. An appropriately designed auxiliary electrode is located between the anode and the cathode. The anode and/or the electrode set on the other side of the cathode can be constituted by the walls of the vacuum envelope.
