Abstract: A system (12) is proposed for the acceleration of ions to treat Atrial Fibrillation (AF), arteriovenous malformations (AVMS) and focal epileptic lesions; this system (12) includes a pulsed ion source (1), a pre-accelerator (3) and one or more linear accelerators or linacs (5, 6, 7) operating at frequencies above 1 GHz with a repetition rate between 1 Hz and 500 Hz. The particle beam coming out of the complex (12) can vary (i) in intensity, (ii) in deposition depth and (iii) transversally with respect to the central beam direction. The possibility of adjusting in a few milliseconds and in three orthogonal directions, the location of each energy deposition in the body of the patient makes that system of accelerators (12) perfectly suited to irradiation of a beating heart.

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.

Abstract: A complex of proton accelerators, includes the following functionally interconnected components: a proton source, a cyclotron, at least one target, located either internally or externally to the cyclotron, a medium energy beam transport magnetic channel, a radiofrequency linear accelerator, a high energy beam transport channel towards an area dedicated to the irradiation of tumors with proton beams, as well as a modular system for supplying radio frequency power capable of feeding, independently two or more accelerating modules of the linac. An integrated computerized system controls the complex of accelerators so to carry out, either in alternation or simultaneously, both the production of radioisotopes—for medical, industrial and therapeutical purposes—and the therapeutical irradiation of, even deep seated tumors.

Abstract: System for ion acceleration for medical purposes comprising a conventional or superconducting cyclotron, a radiofrequency linear accelerator (Linac), a Medium Energy Beam Transport line (MEBT) connected, at the low energy side, to the exit of the cyclotron, and at the other side, to the entrance of the linear radiofrequency accelerator, as well as a High Energy Beam Transport line (HEBT) connected at high energy side to the radiofrequency linear accelerator exit and at the other end, to a system for the dose distribution to the patient. The high frequency of operation of the Linac allows for a reduced consumption and a remarkable compactness facilitating its installation in hospital structures. The use of a modular LINAC allows varying in active way the energy and the current of the therapeutic beam, having a small emittance and a time structure adapted to the dose distribution based on the technique known as the “spot scanning”.

Abstract: A drift tube linear accelerator (linac) that can be used for the acceleration of low energy ion beams. The particles enter the linac at low energy and are accelerated and focused along a straight line in a plurality of resonant accelerating structures interposed by coupling structures up to the desired energy. In the accelerating structures, excited by an H-type resonant electromagnetic field, a plurality of accelerating gaps is provided between drift tubes supported by stems, for instance alternatively horizontally and vertically disposed. A basic module composed of two accelerating structures and an interposed coupling structure, or a modified coupling structure connected to a RF power generator, is if necessary linked to a vacuum system and equipped with one or more quadrupoles.
