Abstract
The utility model discloses a photomultiplier tube for an alpha and beta surface contamination detector, which comprises a photomultiplier tube body (1), wherein a damping ring (2) is arranged on the front part of the photomultiplier tube body (1). The photomultiplier tube for the alpha and beta surface contamination detector has advantages of ingenious structure design and convenience for manufacture and installation; and by adopting the photomultiplier tube, the accuracy of detection to alpha and beta grains can be ensured, and the problem of intertrack crosstalk is solved.
Description
Technical field
The utility model relates to a kind of α, β surface contamination detector, particularly a kind of photomultiplier.
Background technology
At present, the photomultiplier that is used for α, β surface contamination detector comprises mainly-body that said body directly is connected with scintillator through silica gel, though be to connect like this, the device of fixing and compressing useless.Can't in engineering, use; Whether photomultiplier and scintillator coupling be closely reliable; There is very big influence in accurate detection to α, β particle, can cause serious intertrack crosstalk problem simultaneously, uses the degree of accuracy of measurement data to guarantee; Fixation procedure at photomultiplier can not be rotated, and prevents twisted wire.
The utility model content
The purpose of the utility model just provides a kind of photomultiplier that is used for α, β surface contamination detector that can effectively solve α, β particle measurement efficient and intertrack crosstalk problem.
The purpose of the utility model is to realize that through such technical scheme a kind of photomultiplier that is used for α, β surface contamination detector comprises the photomultiplier transit tube body, is provided with shock absorbing ring in the front portion of photomultiplier transit tube body.
Further, said afterbody at the photomultiplier transit tube body is provided with spring attachment.
Wherein, said spring attachment comprises the photomultiplier transit base, and an end of said photomultiplier transit base is connected with the photomultiplier transit tube body; The other end is provided with poly (methyl methacrylate) plate; The outer face of said poly (methyl methacrylate) plate is provided with plate A, the said plate A pillar of packing into, and pillar is provided with printed board; The outer face of said plate A is provided with pillar; Said on pillar, overlapping is provided with holddown spring, and said on the other end of pillar, the setting is that mount pad is arranged, and said outer face at mount pad is provided with mounting receptacle.
Owing to adopted technique scheme, the utlity model has structural design ingenious, make convenient installation, adopt it not only can guarantee accuracy, but also solved the problem of intertrack crosstalk α, β detection of particles.
Description of drawings
The description of drawings of the utility model is following:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the A-A cut-open view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done further detailed explanation; But the utility model is not limited to these embodiments; Any on the present embodiment essence spirit improvement or substitute, still belong to the utility model claim scope required for protection.
Embodiment 1: like Fig. 1, shown in 2, a kind of photomultiplier that is used for α, β surface contamination detector comprises photomultiplier transit tube body 1, is provided with shock absorbing ring 2 in the front portion of photomultiplier transit tube body 1.
In the utility model, shock absorbing ring 2 directly is connected with scintillator through screw, wherein, shock absorbing ring 2 and spring attachment played guiding, fix and the effect of damping, has so just increased the accuracy of α, β detection of particles, has improved efficient.
In the utility model, be provided with spring attachment at the afterbody of above-mentioned photomultiplier transit tube body 1.
Further, said spring attachment comprises photomultiplier transit base 3, and an end of said photomultiplier transit base 3 is connected with photomultiplier transit tube body 1; The other end is provided with poly (methyl methacrylate) plate 4; The outer face of said poly (methyl methacrylate) plate 4 is provided with plate A5, the said plate A5 pillar 6 of packing into, and pillar 6 is provided with printed board 7; The outer face of said plate A5 is provided with pillar 9; Said on pillar 9, overlapping is provided with holddown spring 10, and said on the other end of pillar 9, the setting is that mount pad 11 is arranged, and said outer face at mount pad 11 is provided with mounting receptacle 12.
Through compressing of holddown spring 10, make photomultiplier transit tube body 1 tightr with the coupling of scintillator, simultaneously, also played the effect of damping; The mode that links to each other with the outside through mount pad 11 and screw has well solved the problem of twisted wire, after holddown spring 10 compresses, directly is screwed, and luminous point multiplier tube body 1 no longer rotates, and has effectively avoided twisted wire, has prevented the generation of intertrack crosstalk problem.
