Self-shielded vertical proton linear accelerator for proton-therapy

摘要

A linear proton accelerator including a plurality of accelerator components (10) arranged after one another, and comprising a proton source (11) and a plurality of accelerating units (15, 17). The accelerator further includes a reticular support structure (20) for supporting the accelerator components; the support structure is shaped as a prism with a polygonal cross-section, and has a plurality of side faces (21) joining opposite ends of the prism. The support structure is arranged concentrically with respect to the accelerator components.
