The beneficial effect of the utility model: small, quality is light, can be convenient place on the measuring point, and can guarantee to examine measuring point position's accuracy, the risk can also the lowering apparatus damaged.
Description
Technical field
The utility model relates to a kind of accelerator head leakage rediation proving installation.
Background technology
Accelerator head compromising emanation is the necessary test item of accelerator test item, needs the radiation detection completing 24 points under accelerator open state on the sphere of distance focal point 1m.Existing method is exactly the point utilizing conventional radiation detection instrument to be placed on setting, point point completes detection, need during detection repeatedly to pass in and out machine room, and on predetermined check point, lay detecting instrument very inconvenient, need to configure a lot of support and just can complete.If the accelerator that leakage rate is larger, exceed the range ability of conventional radiation detecting instrument possibly, if do not know in advance, not only can not Measurement accuracy, also can damage detecting instrument.
Summary of the invention
The utility model provides that a kind of volume is little, quality is light, measure accelerator head leakage rediation proving installation accurately.
The technical solution adopted in the utility model is:
Accelerator head leakage rediation proving installation, comprise one and be arranged on thermoluminescent dosemeter on the check point of accelerator head, it is characterized in that: described thermoluminescent dosemeter comprises thermoluminescence element and measuring box, described thermoluminescence element is that thermoluminescence material is wrapped to form ball-shaped structure by glass, and described measuring box is the organic glass ball be wrapped in outside thermoluminescence element.Outside the function of measuring box apart from packaging thermoluminescence element, also play electronic equilibrium effect, namely as buildup material, therefore the material of measuring box must select the equivalent material of water, the water equivalent material of most economical material benefit is exactly polymethylmethacrylate (PMMA), i.e. organic glass.Because thermoluminescence element has directivity when receiving ray, therefore thermoluminescence material (white powder) is become ball-shaped with glass-coated, so just have isotropic nature, the wall thickness of glass bead is 0.5mm, and internal diameter is 3mm, and active volume is 14mm
3.Due to needs isotropy, therefore, measuring box is also made into organic glass ball.
Further, described thermoluminescence element adopts the thermoluminescence material of muting sensitivity, such as LiF:Mg, Ti material (white powder).Because accelerator head compromising emanation amount is comparatively large, and energy is high, and therefore thermoluminescence element adopts the thermoluminescence material of muting sensitivity.
Further, the glass of described thermoluminescence element adopts the glass that thermal behavior is excellent, is because thermoluminescence element needs to be heated rapidly to about 300 DEG C when detecting.
Further, two hemisphere of described measuring box are connected by coupling bar, when according to ray energy determination measuring box, facilitate measuring box to assemble and thermoluminescence element is wrapped in the inside.The thickness of described measuring box is determined according to the energy of ray, for the ray of different-energy, the buildup material variable thickness sample that test maximum dose point needs, therefore detect hour hands and corresponding measuring box is selected to ray energy, such as, when detecting the X ray of 10MV, be just the organic glass ball of 15mm with radius, because the maximum dose point of 10MVX ray is 15mm place under water.
The beneficial effects of the utility model: volume is little, quality is light, can be placed on measurement point easily, and can ensure the accuracy of check point position, can also the risk damaged of lowering apparatus.
Accompanying drawing explanation
Fig. 1 is the structural representation of thermoluminescent dosemeter of the present utility model.
Fig. 2 is the episphere structural representation of thermoluminescent dosemeter of the present utility model.
Embodiment
Below in conjunction with specific embodiment, the utility model is further described, but the utility model is not confined to these embodiments.One skilled in the art would recognize that the utility model covers all alternativess, improvement project and the equivalents that may comprise in Claims scope.
With reference to Fig. 1, Fig. 2, accelerator head leakage rediation proving installation, comprise one and be arranged on thermoluminescent dosemeter on the check point of accelerator head, described thermoluminescent dosemeter comprises thermoluminescence element 1 and measuring box 2, thermoluminescence material is wrapped to form ball-shaped structure for glass by described thermoluminescence element 1, and described measuring box 2 is for being wrapped in the organic glass ball outside thermoluminescence element 1.Outside the function of measuring box 2 apart from packaging thermoluminescence element 1, also play electronic equilibrium effect, namely as buildup material, therefore the material of measuring box 2 must select the equivalent material of water, the water equivalent material of most economical material benefit is exactly polymethylmethacrylate (PMMA), i.e. organic glass.Because thermoluminescence element 1 has directivity when receiving ray, therefore thermoluminescence material (white powder) is become ball-shaped with glass-coated, so just have isotropic nature, the wall thickness of glass bead is 0.5mm, and internal diameter is 3mm, and active volume is 14mm
3.Due to needs isotropy, therefore, measuring box 2 is also made into organic glass ball.Thermoluminescent dosemeter volume is little, and quality is light, can be placed on the position wanted very easily.
Thermoluminescence element 1 described in the present embodiment adopts the thermoluminescence material of muting sensitivity, such as LiF:Mg, Ti material (white powder).Because accelerator head compromising emanation amount is comparatively large, and energy is high, and therefore thermoluminescence element adopts the thermoluminescence material of muting sensitivity.
The glass of thermoluminescence element 1 described in the present embodiment adopts the glass that thermal behavior is excellent, is because thermoluminescence element needs to be heated rapidly to about 300 DEG C when detecting.
Two hemisphere of measuring box 2 described in the present embodiment are connected by coupling bar 3, when according to ray energy determination measuring box, facilitate measuring box 2 to assemble and thermoluminescence element 1 is wrapped in the inside.Described in the present embodiment, the thickness of measuring box 2 is determined according to the energy of ray, for the ray of different-energy, the buildup material variable thickness sample that test maximum dose point needs, therefore detect hour hands and corresponding measuring box 2 is selected to ray energy, such as, when detecting the X ray of 10MV, be just the organic glass ball of 15mm with radius, because the maximum dose point of 10MVX ray is 15mm place under water.
When the utility model uses, accelerator head is determined 24 check points, each check point place is all placed with thermoluminescent dosemeter, thermoluminescent dosemeter described in the present embodiment is suspended on check point by plastic bar, each thermoluminescent dosemeter carries out leakage rediation detection to check point simultaneously, detect terminate after take off thermoluminescent dosemeter carry out data survey read.The thermoluminescent dosemeter cost that the utility model uses is low, can be placed on check point easily, disposablely can detect required point, substantially increases detection efficiency, and can ensure the accuracy of check point position, can also the risk damaged of lowering apparatus.
