Abstract
An accelerator directs an electron beam to a scanner which operates under microprocessor control to convert the beam into two (2) sets of spaced electron beamlets. A magnetic lens deflects the sets of beamlets to a spaced and substantially parallel relationship. A first dipole directs the first set of beamlets in a first direction to a first side of an article. A second dipole directs the second set of beamlets, in a second direction opposite to the first direction, to a second side of the article opposite to the first side of the article. In this way, a single accelerator irradiates two (2) opposite sides of the article with an enhanced precision, simplified controls, a significantly reduced number of components and reduced costs relative to the systems of the prior art. The electron beam may be converted to an x-ray beam which is then processed in the manner described above.
