Abstract
An apparatus and a method for sorting scrap metal containing at least two categories of metals are provided. An x-ray beam is directed towards at least a portion of a particle of scrap metal. Backscattered x-rays, forward scattered x-rays, and transmitted x-rays from the particle are measured and input into a classifier, such as a database with a cutoff plane. The scrap metal is sorted into a first category and a second category on the scrap metal by a controller. An x-ray source for a scanning system is provided with an electron beam generator, an electromagnetic beam focusing coil, a pair of saddle shaped beam steering coils, and a target foil to create a scanning x-ray beam along a plane.
