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 insulating tube (9) has one end and the other end. An avalanche photodiode (APD) (15) is disposed outside the one end of the insulating tube (9). The other end of the insulating tube (9) is hermetically connected to an outside flange through a stem inner wall (61). Capacitors (C1, C2) electrically connected to the APD (15) are provided inside the insulating tube (9) and serve to remove the DC current from the signal generated by the APD (15) when it detects electrons. Since the capacitors (C1, C2) are provided inside the insulating tube (9), the response of the output signal is prevented from degrading.

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.
