Example Embodiment

[0015] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0016] The titanium film protection technology of the electron irradiation accelerator proposed by the present invention includes two design schemes, one is a single lens plus scanning magnet scheme, and the other is a double quadrupole lens scheme. The two schemes can be combined in an embodiment of an electron irradiation accelerator to make the accelerator work more reliably.

[0017] like figure 1 As shown, this embodiment is an electron irradiation accelerator with a titanium film protection function combining two schemes, including an acceleration tube 1 connected to an electron gun, and the acceleration tube 1 is connected to the scanning box through an electron vacuum transmission pipeline 10 8 are connected, the front end of the scanning box 8 is provided with a scanning magnet 7, and the outlet of the scanning box 8 is provided with a titan...

Abstract

The invention relates to the technology of electronic accelerators, in particular to an electronic irradiation accelerator with a titanium film protecting function. The electronic irradiation accelerator structurally comprises an accelerating tube connected with an electronic gun, the accelerating tube is connected with a scanning box through an electronic vacuum transmission pipeline, a scanning magnet is arranged at the front end of the scanning box, and a titanium film is arranged at an outlet position of the scanning box. A single lens for expanding electron beam spots is arranged on the electronic vacuum transmission pipeline outside an outlet of the accelerating tube. When the single lens is a quadrupole lens, a second quadrupole lens can be arranged on the electronic vacuum transmission pipeline at the rear side of the quadrupole lens. A plurality of accelerator components are used for expanding the beam spots, failure of any one component can not cause puncture of the titanium film, and the possibility that two components fail simultaneously is small, so that working reliability of the electronic irradiation accelerator is guaranteed.

Description

technical field [0001] The invention relates to electron accelerator technology, in particular to an electron radiation accelerator with titanium film protection function. Background technique [0002] Electron irradiation accelerator is a kind of electron linear accelerator, its working principle and process are: electrons are first emitted from the electron gun under the action of electrostatic field, after entering the accelerator, they are continuously accelerated under the action of microwave field, and are accelerated to several After a Mev is output from the acceleration tube, it passes through the transmission of the floating space and the deflection of the scanning magnet, passes through a triangular vacuum scanning box and a thin strip-shaped titanium film, and finally bombards the irradiated object. These intense high-energy electron beams hit the irradiated items, producing very high radiation doses. If the irradiated item is food, all the bacteria in it will be...
