Variable energy linear accelerator
First Claim
1. A device for use in a linear accelerator operable to accelerate charged particles along a beam axis, the device comprising a first end section, a second end section, and a transition section interposed between the first and second end sections, the sections being connected together to form a plurality of accelerating cavities aligned along said beam axis and coupling cavities, wherein the first and second sections are configured to operate in fixed collective resonant modes and the transition section is tunable such that different resonant modes of the transition section may be tuned to lie at generally the same frequency as the resonant modes of the first and second sections.

Abstract
A device for use in a linear accelerator operable to accelerate charged particles along a beam axis. The device includes a first end section, a second end section, and a transition section interposed between the first and second end sections. The sections are coupled together to form a plurality of accelerating cavities aligned along the beam axis. The first and second sections are configured to operate in a fixed collective resonant mode and the transition section is tunable such that resonant modes of the transition section may be tuned to lie at generally the same frequency as the resonant mode of the first and second sections.
