Abstract: PROBLEM TO BE SOLVED: To improve cooling efficiency, while preventing the dispersion of heat used to extract cooling in a support member by supporting a support board with support board supporting projections provided in a notch part, so as to reduce a contact area of the support board with the support member. SOLUTION: In a side-on type cooling photomultiplier, a support board 5 formed with a photoelectric negative electrode material 4 in a surface thereof is cooled by a Peltier effect element provided in a vertex of a tube 1. An upper- end part of the support board 5 is cooled through a holding mechanism, and a central part and a lower end thereof are supported by the only four supporting projections provided in a notch part 10a of a first insulating board 10 and four supporting projections provided in a notch part of a second insulating board provided under the tube 1 and having the same shape as the projections of notch part 10a so that a contact area with both the insulating board is remarkably reduced. With this structure, dispersion of the cooling heat used to extract cooling by the Peltier effect element in the first insulating board 10 and the second insulating board is prevented, so as to effectively cool the photoelectric negative electrode material 4, and generation of thermoelectrons from a photoelectric surface is lowered.

Abstract: PROBLEM TO BE SOLVED: To provide a photomultiplier tube of a micro structure realizing stable detection accuracy.
SOLUTION: The photomultiplier tube is provided with an envelope with the inside maintained in vacuum, in which, a photoelectric face (22), an electron multiplier (31), and an anode (32) are arranged. Especially, one or more control electrodes (320) arranged in an inside space of the envelope surrounding the electron multiplier (31) and the anode (32) are electrically connected through one or more connecting parts extended from electron emission ends of the electron multiplier (31). In this structure, voltage impressed between an electron incident end and an electron emission end of the electron multiplier (31) is impressed between the electron incident end and the control electrode, so that a potential gradient gradually increasing from a photoelectric face (22) side toward an anode (32) side is formed at the electron multiplier (31), and at the same time, a substantial potential difference is given between the electron emission end of the electron multiplier and the anode (32) to have stable detection accuracy obtained.

Abstract: PROBLEM TO BE SOLVED: To provide a photomultiplier tube having an improved yield at the time of manufacturing and an improved airtightness of a sealed container by improving integration between bypass lines and a light-receiving face plate, and its manufacturing method. SOLUTION: In this photomultiplier tube 1, the upper ends of bypass lines 2 are formed in a polygonal shape by warped-up plural frame parts 80, and each corner 81 is positioned at a higher position than other parts. As a result, the upper ends 81a of the corner parts 81 are buried deeply in a light-receiving face plate 3, to thereby distribute to improvement of the joining state between the bypass lines 2 and the light-receiving face plate 3. And besides, as the upper ends of the bypass lines 2 are buried in the light-receiving face plate 3, joining between the bypass lines 2 and the light-receiving face plate 3 becomes certain and an yield at the time of a joining work is improved.
