摘要
A linear accelerator for charged particles includes a plurality of accelerating stages in a linear arrangement along a central axis. Each accelerating stage has at least one passageway radially spaced from the central axis for transmitting a beam of charged particles. Electromagnetic wave energy is coupled to the accelerating stages to produce an accelerating electric field in a region of the passageway of each of the accelerating stages. Coupling circuits couple the electromagnetic wave energy between adjacent accelerating stages. Each accelerating stage may be configured as an annular accelerating cavity or as two or more accelerating cavities disposed around the central axis. The passageway may be configured as two or more discrete apertures or a single annular aperture. Beam bending devices may be used to direct the charged particle beam through the accelerator two or more times. The linear accelerator produces a high current, high energy charged particle beam.
