    • 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.
    • 一种电子管(1),其中绝缘管(9)的一端向壳体(2)的内部突出,并且雪崩光电二极管(APD)(15)设置在绝缘管的一端 9)。 绝缘管(9)的另一端连接到外壳(2)的外杆(6)。 在外壳(2)的内部设置有碱源(27),以便产生碱金属蒸气并在外壳(2)的内壁的预定区域中形成光电表面(11)。 碱源(27)通过分离构件(21',23',26)与绝缘管(9)分离。 当制造电子管(1)时产生的碱金属蒸气由于存在分离构件(21',23',26)而不沉积在绝缘管(9)上。 由于对电子管(1)内的电场的不利影响,外壳(2)和APD(15)之间的耐电压不降低,并且电子进入APD(15)的入射效率的劣化, 在防止。
