Background technology
In the prior art, Chinese patent 95219469.4 discloses a kind of spread pen formula radiant image gas detection apparatus, though this patented technology has possessed detection efficiency, sensitivity is better, the advantage of anti-irradiation, autocollimation long working life, but it is big that its shortcoming is a volume, detector is installed needs big space, and detection efficiency is still not ideal enough.In order to reduce the volume of detector, improve Effect on Detecting.Chinese patent 01259228.5 discloses a kind of cobalt 60 gamma ray source-cesium iodides or cadmium tungstate detector container check system, and wherein employed detector is the solid probe of crystal and photodiode coupling.Adopt the reflection white glues to isolate in the mode of solidifying crystal and photodiode, and this isolation method exist this detector can not solve lucifuge and protection against the tide fully and crosstalk, and the relatively poor shortcoming of vibration-isolating effect.And the solid detector array that German Heyman company, Finland DT company etc. make, be to adopt to form a fundamental measurement unit by a plurality of scintillation crystals, the shortcoming that this measuring unit exists is that passage of scintillation light is crosstalked greatly, the maintenance cost height promptly bad one the tunnel will be changed whole detector array.The applicant has applied for a Chinese patent for this reason, and application number is 02286053.3, and name is called " radiant image solid probe ".Solid detector array with this patented technology composition, though possessed that volume is little, lucifuge, protection against the tide, vibrationproof, installation and maintenance are convenient, detection efficiency is high advantage, but its shortcoming is detector array processes difficulty under the small size situation of forming thus, and the dead band is bigger between the detector.
Summary of the invention
In order to solve above-mentioned problems of the prior art, the applicant provides a kind of radiant image array solid probe at the deficiency that exists in No. 02286053.3 patented technology.Not only volume is little for it, lucifuge, protection against the tide, vibrationproof, installation and maintenance convenient, detection efficiency is high, and can make processes easy, overcomes the bigger problem in dead band between the detector.
In order to realize above-mentioned goal of the invention, the technical solution of the utility model realizes as follows:
The radiant image array solid probe, it comprises scintillation crystal that is formed by cesium iodide or cadmium tungstate and the photodiode that is coupled with it, described scintillation crystal and photodiode are contained by housing.Its design feature is that described housing is made up of metal cover board, metal base plate, front end end cover, rear end cap and biside plate.Be provided with a plurality of flutings of number in the described metal cover board, be equipped with the dividing plate of making by heavy metal material in the fluting, each scintillation crystal is separated a plurality of solid probes of formation.Be equipped with the primer pad between described metal base plate and the photodiode, pass metal base plate and the primer pad is drawn the two poles of the earth of photodiode by the insulator of set each solid probe.Be equipped with the side rubber cushion between the end face of described front end end cover, rear end cap and scintillation crystal, photodiode.
According to above-mentioned technical scheme, described photodiode is that one and each scintillation crystal are coupled or photodiode is that monomer is coupled with each scintillation crystal respectively.
According to above-mentioned technical scheme, adopt screw retention between described front end end cover, rear end cap and metal cover board, the metal base plate.Be equipped with the sheet metal lucifuge layer of band conducting resinl between biside plate and metal cover board, the metal base plate and adopt sealing to be adhesively fixed.
The utility model is owing to adopted above-mentioned structure, form housing by metal cover board, metal base plate, front end end cover, rear end cap and biside plate, and the photodiode that will count a plurality of scintillation crystals and coupling with it contain to form solid detector array, makes processing technology simplify and overcome dead band between each detector.Because the partition made by heavy metal in housing separates each scintillation crystal and make each sheet stretch out the scintillation crystal suitable length, thereby greatly reduce and harass and the incoherent scattering of incident ray.Owing on the make described metal cover board, metal base plate and rear end cap can be adopted thicker sheet metal, can make solid detector array play fixation so on the one hand, reduced scintillation crystal scattering on every side on the other hand.Have the sheet metal lucifuge layer of conducting resinl and seal bondingly because adopt at the two ends of housing, one side makes the complete lucifuge of solid detector array like this, has increased the electromagnetism interference free performance of solid detector array on the other hand.Be equipped with primer pad and side rubber cushion owing in the housing in addition, thereby improved the vibrationproof performance of solid detector array.The utility model compared with prior art, not only processing technology is simple, do not have the dead band between each detector, and in anti-scattering, anti-ly harass, performance increases again aspect the lucifuge, protection against the tide, vibrationproof.For the detector that uses the coupling of single photodiode and single scintillation crystal to form, can also be changed by single detector during maintenance, need not destroy a fundamental measurement unit, make and check that fault is very convenient, greatly reduce maintenance cost.
Below in conjunction with accompanying drawing and concrete embodiment the utility model is described further.
