In ion therapy, gantries play a crucial role in minimizing damage to healthy tissue and enabling treatment from diverse angles. The introduction of superconducting magnets results in a substantial reduction in the overall weight and the power required to operate of these otherwise huge structures. [...]

Superconducting magnets technology for a European heavy ion gantry
/ Prioli, Marco (LASA, Segrate) ; Santini, Carlo (LASA, Segrate) ; Barna, Daniel (Wigner RCP, Budapest) ; Gusvitskii, Todor (Rome U.) ; Perini, Diego (CERN) ; Bianchi, E (INFN, Genoa) ; Felcini, Enrico (CNAO, Milan) ; De Matteis, Ernesto (LASA, Segrate) ; Toral, Fernando (Madrid, CIEMAT) ; Levi, Filippo (INFN, Genoa) et al.
Various initiatives in Europe have been launched to study superconducting magnets for a rotatable gantry suitable to deliver up to 430 MeV/u carbon ions for hadron therapy. Different technologies and layouts are being considered: the baseline solution is developed within the EuroSIG collaboration and consists of a strongly curved cos-$\theta$ dipole based on the classical NbTi superconductor.

Strongly curved super-conducting magnets: beam optics modeling and field quality
/ Benedetto, E (Unlisted, CH) ; Barna, D (Wigner RCP, Budapest) ; D’Addazio, M (Unlisted, IT) ; Maria, R De (CERN) ; Felcini, E (Unlisted, IT) ; Frisella, G (Unlisted, IT) ; Garolfi, L (Unlisted, CH ; CERN) ; Latina, A (CERN) ; Norman, H (Manchester U.) ; Oponowicz, E (CERN) et al.
Superconducting dipoles with a strong curvature (radius smaller than 2 meters, for an aperture of about 100 mm and a length of 1-3 meters) are required for applications where compactness is key, such as the synchrotron and gantry for Carbon-ion therapy developed within the European program HITRIplus.Such magnets challenge several assumptions in the field description and put to the test the range of validity of beam optics codes. In particular, the equivalence that holds for the straight magnets between the transverse multipoles description obtained from the Fourier analysis (used for magnet design and measurements) and the Taylor expansion of the vertical field component along the horizontal axis (used in beam optics) is not valid any longer.

First Winding Trial for the Superconducting Ion Gantry (SIG) Dipole Demonstrator Magnet
/ Prioli, M (LASA, Segrate) ; Bianchi, E (INFN, Genoa) ; Carloni, A G (LASA, Segrate) ; Cereseto, R (INFN, Genoa) ; De Matteis, E (LASA, Segrate) ; Farinon, S (INFN, Genoa) ; Gagno, A (INFN, Genoa) ; Levi, F (INFN, Genoa) ; Mariotto, S (LASA, Segrate ; Milan U.) ; Musenich, R (INFN, Genoa) et al.
The Superconducting Ion Gantry (SIG) project aims to design, construct, and test a curved superconducting dipole demonstrator magnet for an ion gantry (up to a rigidity of 6.6 Tm). The main demonstrator magnet parameters are a dipolar field of 4 T generated into a toroidal aperture with an 80 mm diameter, 1.65 m curvature radius, and 30° angular sector. [...]

In the framework of the euroSIG project and within an international collaboration between CNAO, CERN, INFN, and MedAustron, the design of a novel gantry for hadron therapy based on superconducting magnets and a downstream scanning system has been undertaken. The choice of placing the scanning system downstream of the last superconducting dipole plays a crucial role in the overall layout of the gantry, having a direct impact on its radius, weight, and cost.

A collaboration between CERN, CNAO, INFN, and MedAustron has been formed aiming at designing a light rotating gantry suitable for hadron therapy based on 430 MeV/n carbon ion beams. After a first design for a 3 T dipole field, as the backbone of the gantry magnetic system, now the collaboration is looking at an alternative design, for at least 4 T field with a faster ramp rate.
