Abstract
A rotary accelerator (10) accelerates electrons and discharges them through each of a plurality of discharge ports, electrons discharge from each port having a different energy. The electron beams are channeled to scan horns disposed to irradiate products (14) traveling on conveyers (12). More specifically, some of the scan horns are positioned in pairs with an upper scan horn (18) on one side of the product, and a lower scan horn (20) on an opposite side of the product. A beam splitter splits the electron beam alternately between the two scan horns. Alternately, two scan horns (18, 20) are both disposed on the same side of the product. As yet another alternative, a scan horn (60) is disposed horizontally to irradiate the product from the side. Optionally, one or more of the scan horns includes a x-ray target (26) for converting the electrons into x-rays.
