Description

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. The HITRIplus and I.FAST projects are dedicated to the study of the novel Canted Cosine Theta (CCT) dipoles based on NbTi and also HTS. Common design targets were set to allow a direct comparison of the different solutions: 4 T central field in an 80 mm bore, a curvature radius of 1.65 m, and a ramp rate of 0.15 – 0.4 T/s. The progress in the construction of four different demonstrator magnets is discussed and a preliminary comparison is proposed.
