Abstract:
An electron beam delivery system for directing beam pulses to desired positions on a product that is following a path close to said system, comprising:accelerator means for delivering a pulsed beam of charged particles; and a directing system for controlling the beam, said directing system comprising: power supply means for feeding coils of oppositely situated magnetic cores that define magnets to thereby generate respective magnetic fields in the gap between pairs of oppositely situated core legs, each of said coils being wound around a respective one of said core legs, and each of said core legs including a magnetic pole face, wherein all of said magnets are fixed to a common return yoke such that, upon entrance of said beam pulses into said gap, magnetic fields of consecutive magnets are selectively turned on to bend consecutive pulses of charged particles onto desired positions on the product.
