Patent ID: 8610380

Claim:
An accelerator tile, specifically for acceleration modules in a linac for low energy protons, the modules including a sequence of adjacent tiles, the tile being parallelepiped-shaped with a thickness smaller than the other dimensions and including a first middle cavity, located essentially in the middle of a first face of the tile, a first peripheral cavity on the first face of the tile, located at a first side of the tile with respect to the first middle cavity, a second peripheral cavity on a second face of the tile, opposite to the first face, said second peripheral cavity being located at a second side of the tile, opposite to the first side, with respect to the first middle cavity a second middle cavity on the second face, in a position corresponding to said first middle cavity, the first and the second middle cavities being divided by a partition wall integral with the tile and being arranged asymmetrical with respect to said partition wall, whereby, when the tile is arranged side-by-side with adjacent tiles in a sequence of tiles wherein the first face of a first tile is juxtaposed on the second face of a second tile and wherein first tile and second tile are 180° rotated one with respect to the other around a normal barycentric axis α thereof, the first middle cavity on the first face of the first tile and the second middle cavity on the second face of the second tile define an accelerating cavity while the first peripheral cavity on the first face of the first tile and the second peripheral cavity on the second face of the second tile define a coupling cavity.
