Abstract
A high voltage electronic tube comprises an electrode arrangement comprising an outer electrode formed by a cylindrical metal jacket, an inner electrode supported substantially centrally with respect to said outer electrode by an electrode support arranged in an insulating disc providing a vacuumtight closure for the tube and at least one intermediate electrode formed by a metal sleeve arranged concentrically between the outer and inner electrodes. From a high voltage supply circuit comprising an alternating current source and a multi stage voltage multiplier a ground potential is applied to the outer electrode and a high potential of a significant magnitude is applied to the inner electrode, whereas the intermediate electrode is connected to an intermediate stage of the voltage multiplier for receiving a potential of a magnitude between the potentials applied to the inner and outer electrodes.
