    Abstract: Onto a base member, through which stem pins are passed and holding members are to be joined to the respective surfaces thereof, the stem pins and the holding members are joined by fusion by melting of the base member to arrange a stem with at least three or more layers formed by sandwiching the base member by the holding members. In comparison to a conventional arrangement wherein the stem is arranged as a single layer of glass material and this is melted to fuse the stem pins, the positional precision, flatness, and levelness of both surfaces of the stem are improved.

    Abstract: The invention relates to a photocathode and the like having such structure for holding a photocathode plate on a light transparent member with good reliability and workability. In the photocathode, claw portions of a holding member fixed to the light transparent member is pressed against the lower surface of a supporting plate so that a photocathode plate is sandwiched between the light transparent member and the supporting plate. Thus, the supporting plate is pressed against the photocathode plate, so that the photocathode plate is pressed against the light transparent plate by the supporting plate. This allows the photocathode plate to be held reliably by the light transparent member. This simple configuration further provides good workability in assembling.

    Abstract: A photomultiplier eliminates the reflection of light off of focusing pieces in a focusing electrode and prevents the photocathode from emitting useless electrons in response to such reflected light by including an oxide film formed over the surface of each focusing piece. The oxide film is also formed on the surface of secondary electron emission pieces in the first and second stage dynodes to eliminate the reflection of light off of the secondary electron emission pieces and to prevent the photocathode from emitting useless electrons in response to such reflected light. Further, a light-absorbing glass partitioning part is provided in a light-receiving faceplate to suppress crosstalk between channels.

    Abstract: A focused electron/bombarded hybrid photomultiplier tube comprising a photocathode, focusing electrodes, and a collection anode disposed in a detector body. The collector anode includes a diode for receiving the focused output electron beam from the photocathode. The current gain between the photocathode output current and the detector output signal from the diode is over 1000 at a tube operating voltage of 7 kV. The noise factor has been determined to be 1.1. A hybrid photomultiplier tube includes a photocathode, a photodiode for collecting and multiplying electrons emitted by the photocathode and providing an output signal and electrodes for focusing the electrons on the photodiode. A vacuum envelope encloses a vacuum region between photocathode and the detector. A conductor disposed on or adjacent to a sidewall of the vacuum envelope reduces the effect of electrical charges on the inside wall of the vacuum envelope on the trajectories of the electrons. An ion deflector electrode is disposed adjacent to the photodiode anode and extends photocathode operational life and improves noise factor.

    Abstract: A photomultiplier assembly for use in gamma cameras, for example, includes an array of head-on type photomultipliers disposed in parallel relation to one another. The array of photomultipliers has a plurality of dead spaces, in which reflectors are respectively disposed. The reflector can reflect light which has entered the corresponding dead space to an upper portion of a side wall of aproximate photomultiplier. A side photocathode surface is formed on an inside surface of the upper portion of the side wall of the photomultiplier. Therefore, the light which has entered the dead space is reflected by the reflector and impinges on the side photocathode surface to be converted into photoelectrons.
