Description

Single crystal bar rapid detection tool

Technical field

Nuclear radiation detection technical field is the utility model is related to, more particularly to a kind of single crystal bar quick detection work Dress.

Background technology

Detection of the crystal manufacturer to crystal property at present generally uses sampling observation method, i.e. several privileged sites in crystal bar Several crystal bars are respectively cut out in (such as top, middle part, bottom), only carry out performance test to these crystal bars, if this several Crystal bar performance is qualified, judges that the crystal bar performance that the root crystal bar all sites are cut out is all qualified, when array group installs After, then array progressive can be tested, if it find that there is underproof crystal bar in array, then array is disassembled, replaced Underproof crystal bar is changed, is re-assemblied.

Because the growth of crystal bar is a complicated chemically and physically change procedure, different parts (even same height Degree) crystal property can all have certain difference, therefore unqualified crystal bar occurs in the crystal array that crystal manufacturer has assembled Phenomenon is very universal, generally requires to carry out processing of doing over again to crystal array.Nearest nearly all PET or SPECT manufacturers will Ask the performance of every crystal bar in the crystal array of crystal manufacturer offer will be up to standard, this is added significantly to the production of crystal manufacturer Cost.

The content of the invention

Goal of the invention：In order to overcome the deficiencies in the prior art, it is fast that the utility model provides a kind of single crystal bar Fast detecting tool, it is simple in construction, it is possible to achieve the quick performance detection of single crystal bar, it is ensured that the performance of every crystal bar can Enough reach the requirement for being assembled into final crystal array, crystal array yield rate is substantially improved, it is brilliant so as to reduce the production of crystal manufacturer The cost of volume array.

Technical scheme：To achieve the above object, the technical solution of the utility model is as follows：

Single crystal bar rapid detection tool, including base and upper lid, the base include M × N number of and may be inserted into crystal The well type slot of bar, the sealed bottom of the well type slot are provided with safety glass or acrylic film, the well type slot Middle corresponding insertion single crystal bar, the single crystal bar top are covered with lid.

Further, the size of the single crystal bar is long x mm, wide y mm, high h mm, the chi of the well type slot Very little is long X mm, wide Y mm, deep H mm；0.4mm >=X-x >=0.2mm, 0.4mm >=Y-y >=0.2mm, 6mm >=h-H >=5mm.

Further, the upper lid is metal material, and thickness is about 1cm, the bottom mirror finish processing of upper lid, the depth of parallelism ≤0.2μm。

Further, thickness≤1mm of safety glass or the acrylic film, refractive index >=1.5, light transmittance >= 92%.

Further, the material of the base is white macromolecule resin material, its reflectivity>98%.

Beneficial effect：The utility model is simple in construction, it is possible to achieve the quick performance detection of single crystal bar, it is ensured that every The performance of crystal bar can reach the requirement for being assembled into final crystal array, and crystal array yield rate is substantially improved, so as to drop The cost of low crystal manufacturer production crystal array.By using two sets of duplicate the utility model frocks, a tester Member can use two sets of frocks while detection, while filling crystal bar to be measured, realizes the quick performance detection of single crystal bar.

Brief description of the drawings

Accompanying drawing 1 is structural representation of the present utility model.

Embodiment

The utility model is further described below in conjunction with the accompanying drawings.

Single crystal bar is cut by crystal manufacturer to the crystal bar of cylinder, is polished, polishing forms, for being assembled into Crystal array needed for medical imaging device PET or SPECT detector, in order that these crystal arrays meet related detector Design requirement, the performance of single crystal bar have to pass through detection before crystal array is assembled into.

Detection of the crystal manufacturer to crystal property at present generally uses sampling observation method, i.e. several privileged sites in crystal bar Several crystal bars are respectively cut out in (such as top, middle part, bottom), only carry out performance test to these crystal bars, if this several Crystal bar performance is qualified, judges that the crystal bar performance that the root crystal bar all sites are cut out is all qualified, when array group installs After, then array progressive can be tested, if it find that there is underproof crystal bar in array, then array is disassembled, replaced Underproof crystal bar is changed, is re-assemblied.

Because the growth of crystal bar is a complicated chemically and physically change procedure, different parts (even same height Degree) crystal property can all have certain difference, therefore unqualified crystal bar occurs in the crystal array that crystal manufacturer has assembled Phenomenon is very universal, generally requires to carry out processing of doing over again to crystal array.Nearest nearly all PET or SPECT manufacturers will Ask the performance of every crystal bar in the crystal array of crystal manufacturer offer will be up to standard, this is added significantly to the production of crystal manufacturer Cost.

Such as accompanying drawing 1, the single crystal bar rapid detection tool that the utility model is related to, including base 1 and upper lid 3, it is described Base 1 includes M × N number of well type slot that may be inserted into crystal bar, and the sealed bottom of the well type slot is provided with transparent anti- Safety glass or acrylic film are scratched, insertion single crystal bar 2, the single crystal bar 2 are corresponded in the well type slot Top is covered with lid 3.The size of the single crystal bar 2 is long x mm, wide y mm, high h mm, the chi of the well type slot Very little is long X mm, wide Y mm, deep H mm；0.4mm >=X-x >=0.2mm, 0.4mm >=Y-y >=0.2mm, 6mm >=h-H >=5mm.Institute It is metal material to state lid 3, and thickness is about 1cm, the bottom mirror finish processing of upper lid 3, the depth of parallelism≤0.2 μm.The tempering Thickness≤1mm of glass or acrylic film, refractive index >=1.5.The material of the base 1 is white macromolecule resin material Material, its reflectivity>98%.

Before testing for the first time, base insertion single crystal bar of the tester to two duplicate frocks, then One of them is positioned over to the crystal test platform detector top based on SiPM arrays, it is ensured that each SiPM's and tooling base The bottom safety glass or acrylic film 1 of each well type slot:1 coupling (Air Coupling), covers and is opened after being covered in frock Begin to test.Test removes first frock after terminating, and changes second frock, starts to test second group of crystal bar, waits to be tested As a result underproof crystal bar in first frock is taken out while and is put into defective work receiver, will be closed in first frock The crystal bar of lattice takes out and is put into certified products receiver, starts the new crystal bar to be measured of filling, when the crystal bar of second frock Test is completed, then is changed, successively loop test.

Described above is only preferred embodiment of the present utility model, it should be pointed out that：For the common skill of the art For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and Retouching also should be regarded as the scope of protection of the utility model.
