    Abstract: The present invention relates to an electron tube comprising, at least, a cathode electrode and a face plate having a photocathode which are arranged at one end of a body, and a stem arranged at the other end of the body for defining the position of an electron entrance surface where the electron emitted from the photocathode reaches. The object of the present invention is to provide an electron tube which can reduce its size and has a structure for improving the workability in its assembling process. In particular, the electron tube in accordance with the present invention comprises a bonding ring, provided between the face plate and the cathode electrode, for bonding the face plate and the cathode electrode together. The bonding ring is made of a metal material selected from the group consisting of In, Au, Pb, alloys containing In, and alloys containing Pb.

    Abstract: The electron multiplying device according to this invention comprises an electron multiplying unit (E) including dynodes arranged in a plurality of stages. The electron multiplying unit has an incidence opening (21) for an energy beam to be multiplied to enter through, and has the proximal end secured to a base (13). There is provided a casing (16) for housing the electron multiplying unit. The forward edge of the casing is secured to the base (13), and a space defined by the base and the casing houses the electron multiplying unit. The casing has an entrance window (26) formed at a position opposed to the incidence opening (21). Energy beams enter the electron multiplying unit through the entrance window (26), but the electron multiplying unit itself is housed in the casing to be protected from surrounding air flow and unnecessary energy beams not to be measured.

    Abstract: This invention relates to an electron tube which stabilizes the orbits of electrons accelerated and focused by an electron lens and has a structure for effectively suppressing noise generated due to discharge. This electron tube has, at two ends of an insulating container, a cathode electrode (3) and an anode electrode (6) which constitute the electron lens. Particularly, in the electron tube, one end of the cathode electrode (3) and a photocathode (16) are supported by a conductive member (2,4) arranged at one end of the insulating container (5), and the cathode electrode is electrically connected to the photocathode. The cathode electrode (3) partially extends to a stem (10) along the inner wall (502) of the insulating container (5) and is tapered toward the stem so that the distal end portion of the cathode electrode is separated from the inner wall of the insulating container. Therefore, the electron tube realizes, regardless of the size of the insulating container, a structure for preventing the insulating container from being charged and suppressing discharge followed by light emission between the cathode electrode and the insulating container.
