Abstract

The invention provides a photoelectric detection device transfer manufacturing system and method. The photoelectric detection device transfer manufacturing system comprises a cathode cavity, an anode cavity, a working transmission cavity, a transfer transmission system, a drying oven and a vacuum-pumping system, wherein the cathode cavity, the anode cavity and the working transmission cavity are separated through valves, the cathode cavity and the anode cavity are located on the two sides of the working transmission cavity respectively, the transfer transmission system comprises a horizontal transmission system and a lifting system, and the horizontal transmission system comprises an anode assembly containing device, a cathode assembly containing device and a horizontal transmission device. When a photoelectric detection device is manufactured through the manufacturing system, all other technological processes except the anode assembly assembling process are completed in a clean environment with ultrahigh vacuum, and therefore core devices of an MCP can be prevented from being polluted in the manufacturing process; the MCP anode assembly processing process and the photocathode manufacturing process are independent from each other so that non-cathode parts can be prevented from being polluted by cathode alkali metal and the MCP can be kept in a working state with the optimum performance.

Description

technical field [0001] The invention relates to a photoelectric detection and imaging device transfer manufacturing system, in particular to a transfer manufacturing system of a micro-channel plate-type large-area photomultiplier tube (MCP-PMT). Background technique [0002] The photomultiplier tube is a vacuum device that converts extremely weak optical signals into electrical signals. It is widely used in optical analysis instruments, medical instruments, oil logging, space exploration, high-energy physics, laser applications and other fields. It involves the national economy. multiple industries. [0003] The invention of this patent is mainly aimed at the manufacture of microchannel plate-type large-area photomultiplier tubes for neutrino detection. The schematic diagram of the structure principle of the microchannel plate type large-area photomultiplier tube is as follows: figure 1 , mainly composed of glass shell 1 (about Ф500mm), photocathode, anode assembly (includ...
