Damping device for installing photomultiplier

Abstract

The invention provides a damping device for installing a photomultiplier. The damping device comprises a tube sleeve, a damping separation layer and a jacket, wherein the photomultiplier (13) is nested and fixed in the tube sleeve; the damping separation layer and the jacket sequentially wrap the outer surface of the tube sleeve from the inside to the outside; the damping separation layer is made of an elastic material to achieve flexible connection of the tube sleeve and the jacket; the jacket is provided with a platform for installing the damping device on external equipment; and through holes (16) opposite to a photomultiplier window (23) are formed in the side surfaces of the tube sleeve, the damping separation layer and the jacket and are coaxially arranged. The photomultiplier is assembled by using the damping device, so that the vibration resistance of the photomultiplier is improved, the problem of the fragility of a photomultiplier glass structure is solved and the photomultiplier can be applied to a vehicle-mounted platform, an airborne platform, a spaceborne platform and the like.

Description

technical field [0001] The invention relates to the field of photoelectric detection, in particular to a vibration damping device for installing a photomultiplier tube. Background technique [0002] Photomultiplier tube is a common photodetector, which has the characteristics of high sensitivity and wide detection band, so it is often used in the field of weak light detection, such as detection of Raman scattering, Rayleigh scattering, bioluminescence, chemiluminescence, fluorescence luminescence, etc. . [0003] A photomultiplier tube generally consists of a photocathode, an electron multiplier, an anode, and a glass package. The use of photomultiplier tubes is often limited to the laboratory because of the deposition material on the photocathode, the electron multiplier, the insulating ceramic, and the poor vibration resistance of the glass package. With the expansion of application requirements, it is also necessary to use photomultiplier tubes to measure weak light sig...
