摘要：
An electron beam from an accelerator is injected into a vacuum chamber and bent approximately 90 degrees by an electromagnet, which can be translated along the vacuum chamber and along the propagation direction of the electron beam. Under the influence of the electromagnet, electrons exit the scan chamber through a thin metal vacuum barrier and are directed toward the product to be irradiated. There can be an x-ray converter located between the electron beam and the product. As the electromagnet moves along the scan chamber and along the direction of the electron beam, the bending angle of the electron beam can be adjusted as a function of the position of the electromagnet with respect to the product.
