Problems solved by technology

However, the energy of the electrons in the electron beam is often uneven. Under the action of the Lorentz force in the magnetic field, the energy of the electrons at both ends of the long ribbon-shaped electron beam drawn out is relatively low, so that the absorbed dose of the irradiated article (that is, the dose received The energy) is uneven, affecting the processing quality

Abstract

The invention discloses an article irradiating system and a method thereof. An irradiated article is irradiated twice by means of two article carrying belts moving in opposite directions and channel changers, and a lead-out electronic beam is set to be equal to or larger than the irradiated article. According to the invention, the irradiated article is irradiated by the lead-out electronic beam, the first article carrying belt and the second article carrying belt, which are opposite in moving direction, convey the irradiated article to the lead-out electronic beam, and the channel of the irradiated article is changed through the channel changers, so that the irradiated article is enabled to pass by the lead-out electronic beam twice, the length of the electronic beam is fully used, and the uniformity of the absorbed dose of the article is also considered.

Description

Technical field [0001] The present invention relates to the field of accelerator irradiation. More specifically, the present invention relates to a system and method for irradiating objects using an electron accelerator as a radiation source. Background technique [0002] At present, in the electron accelerator irradiation industry, the use of rays by the under-beam transmission system directly affects the processing quality. This is because after the electrons are accelerated in the electron accelerator, they need to be deflected by the magnetic field to expand into a long strip to form an electron beam, which is then drawn to irradiate the article. The energy of the electrons in the electron beam is often uneven. Under the action of the Lorentz force in the magnetic field, the electron energy at both ends of the long strip-shaped electron beam is low, which makes the irradiated article absorb the dose (that is, accept The energy) is not uniform, which affects the processing qu...
