Ion acceleration system for medical and/or other applications
First Claim
1. An acceleration system for charged nuclear particles with mass number equal or greater than 1, comprising:
- a rotating mechanical gantry structure;
at least one radiofrequency (RF) linear accelerator configured for producing a pulsed ion beam,said accelerator comprising at least one linac section mounted on the rotating gantry structure, the accelerator configured for rotating around an axis to irradiate a target or patient from more than one direction with the produced pulsed ion beam, the produced pulsed ion beam configured for treating a patient tumor or malformation; and
radio-frequency (RF) power generators located outside the rotating gantry structure and connected to the at least one linac section via rotating wave-guide devices.

Abstract
The ion acceleration system or complex (T) for medical and/or other applications is composed in essence by an ion source (1), a pre-accelerator (3) and one or more linear accelerators or linacs (6, 8, 10, 13), at least one of which is mounted on a rotating mechanical gantry-like structure (17). The isocentrical gantry (17) is equipped with a beam delivery system, which can be either ‘active’ or ‘passive’, for medical and/or other applications. The ion source (1) and the pre-accelerator (3) can be either installed on the floor, which is connected with the gantry basement, or mounted, fully or partially, on the rotating mechanical structure (17). The output beam can vary in energy and intensity pulse-by-pulse by adjusting the radio-frequency field in the accelerating modules of the linac(s) and the beam parameters at the input of the linear accelerators.
