This patent describes an apparatus capable of acceleration of electrons to energies of at least 1 MeV at currents of at least 100 A over a time interval of at most 1 ..mu..sec. and pulse repetition rates of up to 20 kilohertz, the apparatus comprising: an electron beam injector for generating focused beam of electrons of energy substantially greater than or equal to0.1 MeV; substantially identical accelerator modules, each module serving to receive the beam of electrons and to increase their kinetic energies by substantially 0.1-1.0 MeV, each module having a module axis that is coaxial with the axis of the electron beam injector, each accelerator module comprising: a toroid of ferromagnetic material, with the axis of the toroid being coaxial with the electron beam injector axis and with the inner diameter of the toroid being sufficient to allow the electron beam produced by the electron beam injector to pass through the hollow center of the toroid along the toroid axis; and a hollow cylindrical electrical conductor, with cylinder axis coaxial with the toroid axis, adjacent to the toroid and making at least one complete turn around the toroid generator, for thereby transporting a voltage pulse about the toroid and abruptly changing the magnetic induction of the toroid ferromagnetic material.
