Abstract: An enclosure (2) has a glass bulb body (4) and a tubular glass bulb base (5). The glass bulb body (4) is composed of a generally spherical upper semispherical portion (4a) and a generally spherical lower semispherical portion (4b). The lower semispherical portion (4a) is connected between the upper semispherical portion (4a) and the glass bulb base (5). On the inner wall of the glass bulb body (4), a photoelectric surface (11) is formed. An avalanche photodiode (APD) (15) is disposed in the glass bulb base (5) in a position nearer to the glass bulb body (4) than the intersection (S) of the imaginary extension curve (I) of the lower semispherical portion (4b) and the axis (Z). When light enters the photoelectric surface (11), the photoelectric surface (11) emits electrons. The electrons are converged near and above the surface of the (APD) (15) by the electric field inside the electron tube (1). Therefore the electrons enter the APD (15) efficiently and are detected.

Abstract: An electron tube (1) in which one end of an insulating tube (9) projects toward the inside part of an enclosure (2), and an avalanche photodiode (APD) (15) is provided to the one end of the insulating tube (9). The other end of the insulating tube (9) is connected to an outer stem (6) of the enclosure (2). An alkali source (27) is disposed inside the enclosure (2) so as to produce alkaline metal vapor and to form a photoelectric surface (11) in a predetermined area of the inner wall of the enclosure (2). The alkali source (27) is separated from the insulating tube (9) by separating members (21', 23', 26). The alkaline metal vapor produced when the electron tube (1) is fabricated does not deposit on the insulating tube (9) because of the presence of the separating members (21', 23', 26). The withstanding voltage between the enclosure (2) and the APD (15) does not lower, and deterioration of the efficiency of entrance of electrons into the APD (15) because of the adverse effect on the electric field inside the electron tube (1) in prevented.

Abstract: PROBLEM TO BE SOLVED: To provide an electron tube easy to manufacture and excellent in detection precision.
SOLUTION: An outer case 2 has a glass bulb main body 4 and a glass bulb base 5. The main body 4 is composed of an upper hemisphere 4a and a lower hemisphere 4b. The upper hemisphere 4a is almost spherically curved. The lower hemisphere 4b is almost spherically curved and connects the upper hemisphere 4a and the base 5. The upper hemisphere 4a, the lower hemisphere 4b and the base 5 are integrally formed. An photoelectric surface 11 is formed on an inner wall of the main body 4. An APD 15 is provided on a main body side of an intersection S between a virtual extension curved surface I and an axis Z of the lower hemisphere 4b inside the base 5. When light enters onto the surface 11, the surface 11 emits electrons. Since the electrons converge in the vicinity of a surface of the APD 15 owing to an electric field in the electron tube 1, the electrons enter efficiently in the APD 15 and are detected.

Abstract: PROBLEM TO BE SOLVED: To provide a photomultiplier excellent in cathode uniformity by supporting the end sections of deposition rods with linear expansion absorbing means, and absorbing the elongation by the linear expansion of the deposition rods generated at the time of excitation heating. SOLUTION: A pair of deposition rods 40 extended in the direction of the tube axis A are provided between a focus disk 31 and a photoelectric surface 20. Linear expansion absorbing means 41 supporting the end sections 40a of the deposition rods 40 and absorbing the elongation by the linear expansion generated when the deposition rods 40 are excitation-heated are provided on the outsides of the end sections 40 a of the deposition rods 40. When a voltage is applied between a pair of linear expansion absorbing means 41, the deposition rods 40 are heated, the evaporated Sb is deposited on the inner face 11a of a light entrance window 11, and the photoelectric surface 20 is formed. The deposition rods 40 are linearly expanded in the axial direction during this process, however the elongation is absorbed by the linear expansion absorbing means 41. The deposition rods 40 are prevented from being bent into a bow shape.
