Photoelectron multiplier

Abstract

A photoelectron multiplier is disclosed in the invention, and comprises a mounting base and a multiplier body, the multiplier is arranged on the left side of the mounting base, limiting columns are connected to the periphery of the right side of the multiplier body in a bolted mode, the right sides of the limiting columns penetrate into the inner cavity of the mounting base, a rapid mounting mechanism is arranged in the inner cavity of the mounting base, the right side of the limiting column is connected with the opposite side of the quick mounting mechanism in a clamped mode, and through grooves are formed in the top and the bottom of the mounting base correspondingly. According to a rapid installation mechanism, a movable frame is arranged to conveniently drive a fixed rod to move, the fixed rod can drive a movable seat to move through a movable rod, so that the movable seat drives a positioning column to rapidly clamp and fix the limiting column, the rapid installation process between the multiplier body and the installation seat is met, the efficiency of installing the multiplier body by a user is improved, and meanwhile, the damage to the installation position when the multiplier body is replaced by the user is reduced.

Description

technical field [0001] The invention belongs to the technical field of multipliers, and more specifically relates to a photoelectron multiplier. Background technique [0002] The photoelectron multiplier is also an electron multiplier tube. It is a vacuum detector that can multiply the incident charge. The photomultiplier is a vacuum electronic device that converts weak light signals into electrical signals. The photomultiplier is used in optical measuring instruments and spectral analysis instruments. [0003] The function of the multiplier can strengthen the weak signal, so the user will install the multiplier in the place where the signal is weak. However, the original multiplier is installed and fixed by bolts when installing, and each bolt needs to be fixed. , thereby prolonging the installation time of the user. At the same time, the frequent installation and disassembly of the multiplier will easily lead to slippage at the joint, thereby reducing the fixing effect of ...

AI Technical Summary

Problems solved by technology

[0003] The function of the multiplier can strengthen the weak signal, so the user will install the multiplier in the place where the signal is weak. However, the original multiplier is installed and fixed by bolts when installing, and each bolt needs to be fixed. , thereby prolonging the installation time of the user. At the same time, the frequent installation and disassembly of the multiplier will easily lead to slippage at the joint, thereby reducing the fixing effect of the multiplier. If the user replaces the multiplier, it will easily cause the multiplier The installed position is damaged, which will affect the installation of the next multiplier. Therefore, those skilled in the art provide a photoelectron multiplier to solve the problems raised in the above-mentioned background technology
