Abstract
A method is described wherein the acceleration of a beam of charged particles is achieved using the properties of conductors to limit the penetration of magnetic and electric fields in short times compared to natural time constants. This allows the use of induction electric fields with a Curl localized to a gap to accelerate particles while coupling the accelerated beam to a power supply. Two methods of coupling the particle beam to the power supply are disclosed as exemplary.
