Collective particle accelerator

Patent ·
OSTI ID:6788461
A method of accelerating charged particles by means of an intense relativistic electron beam (IREB) comprising the steps of: propagating an annular IREB within a longitudinal drift tube and density modulating said beam to obtain a plurality of longitudinally spaced ring-shaped bunches of electrons; forming a rippled magnetic field with a desired wavelength within said tube; passing said modulated beam through said rippled magnetic field to alternately compress and expand said rings of electron bunches in the radial direction; generating forward and backward electric field waves with said beam; and injecting charged particles into said beam, said charged particles having a component of velocity in the longitudinal direction for capture and acceleration of said charged particles by said beam. A particle accelerator which comprises: longitudinal drift tube means having a uniform inner diameter; means for generating an annular IREB and injecting said annular beam into said longitudinal drift tube; means for modulating said beam to obtain bunches of longitudinally spaced rings of electrons; means for forming a longitudinal, rippled magnetic field in axial alignment with said means for modulating said beam and coaxial with said drift tube; means for generating forward and backward electric field waves within said beam; and means for injecting charged particles into said beam, said charged particles having a component of velocity in the longitudinal direction for capture and acceleration of said charged particles by said beam.
