Abstract
A pair of cavities defined within a hollow elongate accelerator body include a first resonant cavity having a first resonant slot through an outer wall thereof, and a second resonant cavity having a second resonant slot through an outer wall thereof. The first resonant slot and the second resonant slot are separated by a void region that extends between the outer wall of the first cavity and the outer wall of the second cavity and is bounded in part by an inner surface of the hollow elongate member. The first and second cavities are coupled to each other through a dual slot coupling structure that includes the first resonant slot, the void region, and the second resonant slot.
Claims22
A system comprising:
- a pair of cavities defined within a hollow elongate member, the pair including a first resonant cavity having a first resonant slot through an outer wall thereof, and a second resonant cavity having a second resonant slot through an outer wall thereof;
- wherein the first resonant slot and the second resonant slot are separated by a void region that extends between the outer wall of the first cavity and the outer wall of the second cavity and is bounded in part by an inner surface of the hollow elongate member;
- and
- wherein the second cavity is coupled to the first cavity through a dual slot coupling structure that includes the first resonant slot, the void region, and the second resonant slot.
A standing wave particle accelerating system, comprising:
- a hollow elongate member extending along a beam axis;
- a plurality of pairs of resonant cavities defined within the hollow elongate member, the cavities interconnected through a beam tube that extends along the beam axis to allow charged particles to pass therethrough;
- wherein each pair of cavities includes:
- a first resonant cavity having a first resonant slot cut through its outer wall, and a second resonant cavity adjacent the first resonant cavity and having a second resonant slot cut through its outer wall;
- and
- wherein the first resonant slot and the second resonant slot are separated by a void region that extends between the outer wall of the first cavity and the outer wall of the second cavity and is bounded in part by the interior surface of the hollow elongate member;
- and
- wherein the second cavity is coupled to the first cavity through a dual slot coupling structure that includes the first resonant slot, the void region, and the second resonant slot.
A method comprising:
- aligning a plurality of pairs of adjacent cavities along a beam axis;
- for each pair, forming a resonant slot on the outer walls of each adjacent cavity, and separating the resonant slots by a void region that wraps around and spans both cavities by about 180 degrees in the azimuthal direction along the beam axis, thereby generating a dual slot coupling structure that includes the two resonant slots and the void region, and that couples the adjacent cavities to each other;
- and
- providing RF power to the plurality of cavities, causing the magnetic fields in the resonant slots in each coupling structure to be coupled and to become confined within the void region, and further causing the dual slot coupling structure to resonate in one or more collective modes in which the electric fields in acceleration gaps defined within the adjacent cavities are out of phase and reversed in direction with respect to each other.
