ABSTRACT:
An area beam of electrons capable of delivering large doses of electron irradiation at small dose rates and having a predetermined distribution pattern is provided by an electron accelerator comprising plural discrete cathodes positioned as required to achieve the desired pattern. An individual emission control is provided for the filament of each cathode. In a preferred embodiment plural cathodes are movably mounted in a row extending transversely of the transport path of material to be irradiated, a plurality of such rows being positioned along the direction of transport.
