    摘要： A high-brightness, space-charge-dominated circular charged-particle beam system includes a flat circular emitter that emits charge particles to form a space-charge-dominated circular charged-particle beam. The space-charge-dominated circular charged-particle beam is emitted from the flat circular emitter with a uniform density and having a current emission being space-charge-limited, obeying the Child-Langmuir law. A diode includes at least one electrode at the flat circular emitter and at least one additional electrode that accelerates the charged particles. A beam tunnel is coupled electrically to at least one of the additional electrodes. An applied axisymmetric magnetic field focuses the space-charge-dominated circular charged-particle beam. A depressed collector collects the space-charge-dominated circular charged-particle beam.

    摘要： A permanent magnet focusing system includes an electron gun that provides an electron ribbon beam having an elliptical shape. A plurality of permanent magnets provide transport for the electron ribbon beam. The permanent magnets produce a non-axisymmetric periodic permanent magnet (PPM) focusing field to allow the electron ribbon beam to be transported in the permanent magnet focusing system.

    摘要： A RF amplifier includes a RF input section for receiving a RF input signal. At least one single-sided slow-wave structure is associated with the RF interaction section. An electron ribbon beam that interacts with the RF input supported by the at least one single-sided slow-wave structure so that the kinetic energy of the electron beam is transferred to the RF fields of the RF input signal, thus amplifying the RF input signal. A RF output section outputs the amplified RF input signal.
