MULTI ANODE-TYPE PHOTOELECTRON INTENSIFIER TUBE AND RADIATION DETECTOR

摘要

A measurement tube (11) integrally comprises along its tube axis a tube head section (17), a funnel-shaped connection section (15), and a tube main body section (13). The size of a cross section substantially perpendicular to the tube axis of the tube head section is larger than the size of a cross section substantially perpendicular to the tube axis of the tube main body section. The curvature radius of each bent corner of the tube head section is smaller than the curvature radius of each bent corner of the tube main body section. The length of the tube head section along its tube axis is shorter than the length of the tube main body section along its tube axis. A photoelectric surface (20) is formed in a region located inside the tube head section on a face on the side to which the tube head section of an incidence face plate (9) is connected. A multi anode-type photoelectron intensifier tube (1) enables effective incidence of light in the photoelectric surface and has high strength.
