Cavity accelerator self-focusing of particles loaded

摘要

The invention relates to a cavity accelerator self-focusing loaded particles, for constituting the first or the single cavity (ca) of a structure accelerator linear 1; this structure 1 for accelerate a beam of particles loaded according to an axis coincident with a longitudinal axis 3 of this structure. The cavity (ca) according to the invention comprises a wall of the input 8 tilted in the longitudinal axis 3 of a manner to form a surface of revolution 10, allowing a focusing effect of the particles loaded.
