Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of irradiation accelerator detection equipment, in particular to a tool used for vertical distribution of irradiation dose of an electron accelerator. Background Art
[0002] The electron beam energy output by a large high-energy electron accelerator during irradiation is the core technical indicator of the irradiation device, which directly affects the processing capacity and efficiency of the irradiated product. Energy detection is a key point in daily quality control of irradiation processing. Conventional energy detection uses an aluminum sheet stacking method, in which aluminum sheets and CTA dose sheets are alternately stacked and irradiated after being tightened with screws. The operation of this detection method is relatively complicated, and the CTA metering sheet is required to be placed in the center. Therefore, it is difficult to ensure that it is exactly the same in actual operation, which affects the accuracy of the detection results. To this end, we propose a tooling for the vertical distribution of electron accelerator irradiation dose. Utility Model Content
[0003] The utility model aims to provide a tool for vertical distribution of irradiation dose of an electron accelerator to solve the problems raised in the above-mentioned background technology.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tool for vertical distribution of irradiation dose of an electron accelerator, comprising a tool body, a plurality of step portions are arranged in sequence on the tool body, a placement groove for placing a CTA detection sheet is opened on the step portion, a base is arranged at the bottom of the tool body, the top of the base is connected to a telescopic rod through a pull rod, the telescopic rod is connected to the bottom of a mounting seat, the mounting seat is movably connected to the lower side of a track, and a detection mechanism is installed below the mounting seat.
[0005] In the above solution, casters are arranged below the base.
[0006] In the above scheme, the length, width and height of the placement groove are 60, 40 and 5 mm respectively.
[0007] In the above solution, the limiting block on the top of the mounting seat is movably clamped in the limiting groove below the track.
[0008] In the above solution, a limiting bolt is screwed onto the upper side of the track.
[0009] In the above solution, the height of the tool body is 540 mm.
[0010] In the above solution, the tool body is snap-fitted with the base.
[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: the tooling for vertical distribution of irradiation dose of electron accelerator has a simple and reasonable structural design and strong practicality. The CTA detection piece is placed in the placement slot, and the whole tooling is placed in a pure water medium for beam irradiation. Then, the CTA detection piece after beam irradiation is taken out, and its absorbance value is detected. The corresponding absorption detection is calculated by the change of absorbance value before and after irradiation, and finally the electron beam energy is obtained by data calculation and analysis. By fixing the position of the CTA detection piece in the device, it is ensured that all the detection pieces are fixed in the specified position, and the operation is extremely simple. At the same time, the whole detection fixing device can be placed in a medium with low density for energy detection comparison and analysis. The tooling effectively solves the problem of positioning the CTA detection piece, is easy to operate, and can be placed in media with different densities, and is more widely used.
