Abstract
The utility model discloses a vibration resistance and shock resistance type photomultiplier. The vibration resistance and shock resistance type photomultiplier comprises an electron optical input system (1), an electron multiplication system (2), and an anode output system (3). The electron optical input system (1), the electron multiplication system (2) and the anode output system (3) are installed in a sealed container (4) as a whole. The electron optical input system (1) comprises a light receiving panel (1-1) and a photoelectric surface (1-2). The electron multiplication system (2) is composed of dynodes. The photomultiplier provided in the utility model has advantages of reasonable structural design, good reliability, stable operation, long service life, good strong-shock resistance, good strong-vibration resistance, small size and broad application range, and can be used to overcome shortages with krypton lamps in the prior art.
Description
Technical field
The utility model relates to a kind of photomultiplier, is specifically related to a kind of practical anti-vibration, shock resistance, dependable performance, the photomultiplier of long service life.
Background technology
Photomultiplier is light signal to be converted into to a kind of vacuum light-sensitive device of the signal of telecommunication.The shell of existing photomultiplier is full glass shell, when impact reaches tens g, will cause glass bulb, and particularly blast pipe burns bursting of lamp position and leaks gas.Along with social development, anode luminous sensitivity, dark current, shock resistance, anti-vibration, miniaturization to photomultiplier are had higher requirement, the electron-optical system of prior art part photomultiplier, electron multiplication system and anode output system and airtight container are respectively that discrete is assembled, under thump strong vibration condition, use, electrode size and the relative position of above-mentioned three large systems are offset, cause anode luminous sensitivity to reduce and the dark current rising, even homogeneous tube lost efficacy, useful life is shorter, and cost is high.
Therefore, necessary a kind of reasonable in design of research and development, anti-vibration, shock resistance, dependable performance, the photomultiplier of long service life of designing on the prior art basis.
Summary of the invention
Goal of the invention: the purpose of this utility model is in order to solve the deficiencies in the prior art, and a kind of reasonable in design is provided, and has anti-vibration and shock resistance is strong, and reliability is high, the photomultiplier of long service life.
Technical scheme: in order to realize above purpose, technical solution adopted in the utility model is:
A kind of anti-vibration, shock proof photomultiplier, it comprises the electron optics input system, electron multiplication system and anode output system, described electron optics input system, electron multiplication system and the integral installation of anode output system are in airtight container, described electron optics input system comprises the sensitive surface plate, photoelectric surface, and described electron multiplication system consists of dynode.
As preferred version, anti-vibration described in the utility model, shock proof photomultiplier, the spacing between each dynode in described electron multiplication system is 2 ~ 5mm.
As preferred version, anti-vibration described in the utility model, shock proof photomultiplier, the caliber of described photomultiplier is 25～50mm, length is 50～80mm.
As preferred version, anti-vibration described in the utility model, shock proof photomultiplier, anode and the spacing between the final stage dynode in described anode output system are 0.5～3mm.
Beneficial effect: the anti-vibration that the utility model provides, shock proof photomultiplier are compared and are had the following advantages with the prior art photomultiplier:
The anti-vibration that the utility model provides, shock proof photomultiplier, reasonable in design, reliability is strong, working stability, long service life, there is high anode luminous sensitivity, low-dark current, resisting strong impact, anti-strong motion, plurality of advantages that volume is little, have wide range of applications, can overcome many deficiencies of prior art krypton lamp.
The accompanying drawing explanation
