Abstract

Disclosed is an electron linear accelerator having dual purposes and a dual-purpose method of the electron linear accelerator. The electron linear accelerator comprises an accelerating tube, a scanning box, an industrial computed tomography (CT) and a beam deflection system, wherein the beam deflection system comprises a front quadrupole magnet, a deflection magnet, a rear quadrupole magnet and a scanning magnet; the front quadrupole magnet is arranged behind the accelerating tube, the deflection magnet is arranged behind the front quadrupole magnet, and the rear quadrupole magnet and the scanning magnet are arranged behind the deflection magnet; the industrial CT is arranged behind the rear quadrupole magnet and the scanning box is arranged behind the scanning magnet; and the deflection magnet is controlled to be opened or closed, and electronic beam current is selected for moving forwards in a linear mode or for deflecting at an alpha angle, so that the electronic beam current selectively enters the scanning box or the industrial CT. The electron linear accelerator having dual purposes and the dual-purpose method of the electron linear accelerator solve the problem that the requirements of dual purposes on electron beam spot sizes are contradictory. Under the condition that all performances meet the requirements, the cost is reduced. The electron linear accelerator having dual purposes and the dual-purpose method of the electron linear accelerator not only perform electron beam irradiation by using different energy but also generate X rays with different energy, and perform CT imaging.

Description

technical field [0001] The present invention relates to an electron accelerator. The invention also relates to an application method of the electron linear accelerator. Background technique [0002] At present, in the application of electron linear accelerators, each accelerator generally can only realize one function, which is electron irradiation or X-ray imaging. Electron irradiation plays an important role in the fields of material modification, radiation sterilization, and food preservation, and X-ray imaging plays an irreplaceable role in nondestructive testing, medical diagnosis, and security inspection. When electron beams are used to irradiate items, the electron beam spot is required to be relatively large and the beam current is relatively uniform. Through the action of the scanning magnet and the item conveyor belt, the scanning of the items can be realized. When using X-ray imaging, in order to achieve higher spatial resolution and image clarity, it is require...
