Abstract: The invention is directed to the use of medium to high power (greater than or equal to 1 kW) and medium to high energy (greater than or equal to 1 MeV) electron beam or X-ray to cure coatings in thick complex three dimensional automotive bodies. The medium to high power, medium to high energy has sufficient throughput and penetration to permit curing through multiple layers of steel and, therefore, is able to penetrate shadows caused by the bends, folds and curves in automotive bodies. In addition, the medium to high power, medium to high energy beam has sufficient throughput and penetration to cure the thicker coatings that accumulate in surface cracks and crevices. The invention permits the use of electron beam curable coatings and, thereby, reduces the fire hazard, hazardous air pollutant, and volatile organic problems associated with the non-reactive solvents used in the solvent based paints conventionally employed in the automotive industry.

Abstract: An apparatus for delivering a beam of charged particles along two separate beam paths comprising a pulsed charged particle beam source for producing a series of beam pulses along a first beam path, a switching magnet for developing a magnetic field, and a power supply means for selectively applying current pulses to said switching magnet in timed relation to each of a plurality of predetermined beam pulses effective to develop a constant magnetic field throughout the period of each predetermined beam pulse and deflect each entire predetermined beam pulse from said first beam path to a second beam path.

Abstract: Apparatus and method for attenuating the energy and increasing the angular scattering of a radiation beam particularly suited for electron beams and for promoting dose uniformity in irradiated target products, including using a cooled, intermediate scatter plate which may or may not be perforated and a radiation reflective target basket.

Abstract: A method and system for scanning a beam of charged particles to control radiation dose distributions is implemented by deflecting the beam through a plurality of positions across a conveyor path along which an object to be irradiated is moved, and controlling the length of time the beam remains at each position in accordance with the radiation dose required at each position. The beam may be deflected by a single magnet beam scanning device supplied with a drive signal having a steplike waveform or by a series of sequentially operated, controllable deflection magnets arranged along a beam pipe to sequentially deflect the beam toward the object to be irradiated from different positions.

Abstract: A scanning beam deflection system and method utilizes a beam scanning device for producing rays diverging from a central axis of a beam of charged particles and a deflection magnet assembly for deflecting the scanning beam substantially 270.degree. within an evacuated deflection chamber such that the deflected scanning beam exits an offset beam window in the deflection chamber and has rays diverging from the central axis of the deflected scanning beam at substantially the same angle as the diverging rays produced by the beam scanning device. The system and method is particularly useful for irradiating internal surfaces of hollow articles with the deflection chamber and deflection magnet assembly disposed along an axis of symmetry of the object.
