Abstract

The invention provides a micro-channel plate for a proximity type photoelectric detection device and a preparation method of the micro-channel plate. According to the invention, a NiCr connecting layer, a metal aluminum film layer and an aluminum film surface oxide layer are sequentially formed on the input surface of the micro-channel plate, and the NiCr connecting layer directly covers the surface of the input surface of the micro-channel plate. The detection and collection efficiency of the micro-channel plate is 98% or above; and when the micro-channel plate is applied to the proximity type photoelectric detection device, the detection efficiency of the device can be greatly improved .

Description

technical field [0001] The invention relates to the technical field of vacuum photodetection, in particular to a microchannel plate for close-attached photodetection devices and a preparation method thereof. By adjusting the opening area ratio of the microchannel plate and the surface film structure, the microchannel The collection efficiency of the plate, so as to realize the improvement of the detection efficiency of the proximity photodetection device. Background technique [0002] Among the performance indicators of vacuum photodetection devices, the detection efficiency of effective optical signals is an important indicator. In order to achieve higher detection efficiency, it is necessary to continuously improve the quantum efficiency / sensitivity of the photocathode to convert photons into photoelectrons, and at the same time improve and optimize the microchannel. The collection efficiency of electron multipliers such as plates for photoelectrons. In the process of sol...
