Integrated narrow-frame photoelectric detector and manufacturing method thereof

The invention discloses an integrated narrow-frame photoelectric detector and a manufacturing method thereof, which can be used in the fields of low-light detection, particle detection, nuclear radiation detection and the like, and solve the problems that in the prior art, the effective detection area ratio is difficult to increase by a circular structure of a vacuum photoelectric detector; and a micro-channel plate electron multiplier assembly adopts welding, and an insulating spacer is too thin, so that the insulativity becomes poor. The integrated narrow-frame photoelectric detector comprises a cathode window, a photoelectric cathode, a micro-channel plate electron multiplier, an insulating tube shell, a charge collection anode, an electrode lead and an indium sealing groove. Meanwhile, the invention further provides a manufacturing method of the integrated narrow-frame photoelectric detector, and the integrated narrow-frame photoelectric detector has the advantages of being high in detection efficiency, l
