摘要： Apparatuses and methods for accelerating electrons include a radio-frequency (RF) waveguide configured to couple an RF source to an accelerator that utilizes electron cyclotron resonance acceleration (eCRA). The RF waveguide includes a pair of parallel rectangular waveguides including a first waveguide and a second waveguide and a mode converter coupled to respective ends of the pair of parallel rectangular waveguides. The mode converter includes and outer body and two coaxial cylinders. An electron source is configured to provide a beam of electrons through an inner cylinder. An accelerator includes a RF cavity having a longitudinal axis, a cylindrical outer wall, an inlet, and an outlet and an electro-magnet surrounding the RF cavity and configured to produce an axial magnetic field. The mode converter is configured to excite a rotating TE-111 mode in the RF cavity.
