ELECTRON TUBE

WIPO Patent Application WO/2019/012914

A1

An electron tube (1) is provided with: a photoelectric surface (3) which emits electrons E corresponding to light L; an avalanche photodiode (6) disposed opposite to the photoelectric surface (3); a focusing electrode part (4) which accelerates and converges the electrons E from the photoelectric surface (3) toward the avalanche photodiode (6); and a casing (2) including a stem (9) on which the avalanche photodiode (6) is provided. The stem (9) has a light incidence hole (26) which allows passage of the light L, and the periphery of the light incidence hole (26) is shielded from light by the stem (9). The focusing electrode part (4) includes: a first region (34a) in which a light passage hole (37) is provided; and a second region (34b) in which an electron passage hole (38) for guiding the electrons E to the avalanche photodiode (6) is provided. The first region (34a) is formed on an axial line A1 connecting the light incidence hole (26) and the photoelectric surface (3). The second region (34b) is formed on an axial line A2 connecting the photoelectric surface (3) and the avalanche photodiode (6).
