Rotating-wave electron beam accelerator |
摘要 |
An electron beam accelerator utilizes a single microwave resonator holding a transverse-magnetic circularly polarized electromagnetic mode and a charged-particle beam immersed in an axial focusing magnetic field. The combined effect of the transverse-magnetic microwave fields and the axial magnetic field provide the electron beam with a helical shape and a rotational motion which allows the entire beam to be continually accelerated to high energies in a dc-like fashion. The use of the transverse-magnetic circularly polarized electromagnetic mode allows the resonant frequency to be independent of resonator length-allowing the resonator length to be selected to achieve desired particle acceleration. Using a transverse-magnetic rotating wave mode, TM110, allows the cavity frequency to be independent of cavity length and eliminates the need for bunched beams and short cavities while allowing the use of a spiraling moving beam. The rotating wave electron beam has a number of applications including, for example, a compact, pulsed high energy electron beam generator within tool casing. |
