A triode type cathode structure including a cathode assembly composed of a cathode electrode at least one electron emitter and a resistive layer inserted between the cathode electrode and the at least one electron emitter to connect them together electrically. The triode cathode structure also includes a grid electrode separated from the cathode assembly by a layer of electrical insulation. The cathode electrode is arranged in a first plane and the at least one electron emitter is arranged in a second plane parallel to the first plane and the cathode electrode and each electron emitter are separated by a same distance measured in a third plane parallel to the first and second planes.
