Abstract

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, large in effective detection area ratio and compact in structure, being easy to process and manufacture and the like.

Description

technical field [0001] The invention belongs to the technical field of photoelectric detection and imaging, and in particular relates to a microchannel plate-type photodetector with a large effective detection area and is easy to manufacture, which can be used in the fields of low-light detection, particle detection, nuclear radiation detection and the like. Background technique [0002] Photoelectric detection imaging technology is a technology that converts optical signals into electrical signal detection, and is widely used in various fields of national economy. The microchannel plate is a glass sheet composed of many tiny channels, each channel is equivalent to an independent electron multiplier, which multiplies and amplifies the electronic signal, so that it can detect weak signals, and has fast time response and two-dimensional spatial resolution. Typical photodetector image intensifiers and fast-response photomultiplier tubes are made with microchannel plates as the ...
