    Abstract: PROBLEM TO BE SOLVED: To provide an electron tube capable of a stable operation over a long period of time. SOLUTION: In this electron tube, an opening area of an opening 61 of an anode electrode 60 is formed smaller than an incident area of an electron incident face 44a of a semiconductor device 40, the semiconductor device 40 is constituted so as to have an electron incident face 44a whose conductor type is (p) type and a board 41 whose conductor type is (n) type, electrically connect an (n) type board 41 to a system 31, have the anode electrode 60 and the system 31 with their same potential, and apply a reverse-bias to the semiconductor device 40.

    CPC classification number: H01J31/50

    Abstract: PROBLEM TO BE SOLVED: To provide an electron tube that can be sufficiently improved in dielectric strength characteristics.SOLUTION: An image intensifier 1 includes a vacuum container constituted including a ceramic member and a metal electrode, and a side tube 2 is filmed with an inorganic insulating film including internal surfaces of ceramic rings 15A, 15B, 15C, and 15D, and internal surfaces on electrodes 9A, 9B, 9C, 9E and 9F. In such a configuration, electron emission from a part of the electrodes 9A, 9B, 9C, 9E and 9F on an internal surface of the side tube 2 constituting the vacuum container, and boundary surfaces between the electrodes 9A, 9B, 9C, 9E and 9F and ceramic rings 15A, 15B, 15C, and 15D is reduced to keep output characteristics excellent. Consequently, dielectric strength characteristics of the image intensifier 1 can be improved.
