Abstract
The utility model relates to an X-ray reflection cavity with a novel structure. A main body comprises an outer-layer lead plate and an inner-layer radiation-resistant plastic partition plate, and the X-ray reflection cavity is characterized in that a circle of square annular cavity inner liner which is formed by casting a mixture of boron carbide, carbon and boron, is in flush type fit and in line with the surface on the inner side of the cavity and has a reflection comprehension function is increased on the surface on the inner side of the cavity near the bottom; and by utilizing the physical properties of low atomic mass and high density, the incident X rays can be reflected to an area where the original intensity of the X rays is lower, and the compensation is performed so as to improve the intensity of the X rays in the irradiation area as a whole, enable the intensity of the X rays to be closer to the intensity in the central area, further reduce the error among all positions during the experimental irradiation process and be conductive to improving the homogeneity in X-ray irradiation and the processing quality of objects.
Description
Technical field
The utility model relates to a kind of X ray treatment facility, particularly a kind of structure novel, helps to improve the X ray reflection cavity of sample preparation quality.
Background technology
X ray reflection cavity at present common X ray treatment facility generally is made of outer stereotype 1 and internal layer radiation hardness Plastic securing panel 2, as shown in Figure 1, cavity is originally as rectangular parallelepiped or square, be provided with special-purpose X ray on the top board of top and enter perforation 3, X ray bulb 4 correspondingly is fixedly installed on the outer top surface of top top board.During work, X ray is by entering the tapered divergence form of perforation to intracavitary irradiation, and its irradiated area enlarges from top to bottom gradually, and the cone inside that forms thus is namely the reach of X ray.On each point in this reach, x-ray bombardment intensity is different, the closer to the beam center, from the distance of X ray bulb more close to, the exposure intensity of X ray is larger, the closer to the beam central periphery, from the distance of X ray bulb more away from, x-ray bombardment intensity is also just less.Therefore, there is certain difference in the x-ray irradiation dose of experiencing on perpendicular to the conplane each point of beam center position, when irradiated sample is placed on the cone bottom position, the heterogencity of the x-ray bombardment intensity that is shone by each point thereon, thereby will certainly cause affecting the stability of Disposal quality.So, the X ray reflection cavity of existing structure form relatively is applicable to utilize disinfecting of x-ray inspection, Non-Destructive Testing, extensive biologic material etc. that the treatment dosage homogeneity is required lower or without the use that homogeneity requires, is not suitable for for the scientific experiment aspect that Disposal quality is had stability requirement.
Summary of the invention
The purpose of this utility model is the poor weak point of the existing processing sample quality of X ray cavity consistance that will overcome the existing structure form, a kind of structure novel is provided, helps to improve the X ray reflection cavity that is subjected to product Disposal quality in the same old way, is conducive to enlarge X ray treatment facility work applicable surface.
the X ray reflection chamber body of structure novel of the present utility model is made of outer stereotype and internal layer radiation hardness Plastic securing panel, cavity is originally as rectangular parallelepiped or square, be provided with special-purpose X ray on the top board of top and enter perforation, be characterised in that to increase on the inner surface of the nearly bottom of cavity and be provided with the cavity inner liner that a circle has the reflection compensation function, described cavity inner liner main body with reflection compensation function is the square ring that conforms to cavity inner surface setting-in coupling, by boron carbide, the composite material casting of carbon and boron forms, the weight proportion of its material is carbon (1%-2%), boron (4%-8%), boron carbide (90%-95%).
X ray reflection cavity based on the utility model structure novel of above-mentioned design, due on traditional X ray cavity basis, increased by a circle by take boron carbide as main body and be mixed with the cavity inner liner of certain proportion carbon and boron on the inner surface of the nearly bottom of cavity, with market common boron carbide compound on sale as major ingredient, and the enhancement mode composite material that consists of of the boron blend of mixing therein the carbon of small amount and relatively large ratio, improve the nuclear physics performance of common boron carbide compound with higher boron carbon proportioning, utilize its low atomic mass with high density, high-energy photon to be had the physical characteristics of reflecting effect preferably for the absorption of photon is less, the cavity inner liner of making has the X ray reflection that will incide to the lower zone of X ray intensity originally, compensate, make whole raising of X ray intensity in irradiated region, intensity closer to the central area, thereby reduce the error between each position in the experiment irradiation process, improve the homogeneity of x-ray bombardment and the Disposal quality of article.
