Embodiment Construction

[0066] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0067] like figure 1 As shown, the integrated narrow-frame photodetector of the present invention includes a cathode window 1, a photocathode 2, a microchannel plate electron multiplier 3, an insulating tube 4, a charge collecting anode 5, an electrode lead 6 and an indium sealing groove 7 .

[0068] The insulating tube shell 4 of the present invention is in the shape of a groove formed by a bottom surface 401 and a side surface 402, and can be an integral structure of a cylinder, a rectangular parallelepiped or a cube. The upper end surface of the side surface 402 of the insulating tube shell 4 is sealed with the cathode window 1 through the indium sealing groove 7 to form a vacuum sealed chamber; the electrode lead hole 601 and the anode pin hole 501 are arranged on the bottom surface 401; the clamping slot 403 is arranged on the insulati...

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, etc. The detection area ratio, and the micro-channel plate electron multiplier assembly is welded, the technical problem of poor insulation due to the thin insulating gasket. The integrated narrow-frame photodetector includes a cathode window, a photocathode, a microchannel plate electron multiplier, an insulating tube case, a charge collecting anode, an electrode lead, and an indium sealing tank. At the same time, the present invention also proposes a manufacturing method of an integrated narrow-frame photodetector, which has the advantages of high detection efficiency, large effective detection area ratio, compact structure, and easy processing.

Description

technical field [0001] The invention belongs to the technical field of photoelectric detection and imaging, and in particular relates to a micro-channel plate type photodetector with large effective detection area and easy fabrication, 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 signals for detection, and is widely used in various fields of the 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 the weak signal can be detected, and it has fast time response and two-dimensional spatial resolution capability. Typical photodetector image intensifiers and fast-response photomultiplier tubes are made with microc...
