Next generation ion therapy magnets both for gantry and for accelerator (synchrotron) are under investigation in a re-cently launched European collaboration that, in the frame of the Eu-ropean H2020 HITRIplus and I.FAST programmes, has obtained some funding for work packages on superconducting magnets. De-sign and technology of superconducting magnets will be developed for ion therapy synchrotron and -especially- gantry, taking as refer-ence beams of 430 MeV/nucleon ions (C-ions) with 1010 ions/pulse. The magnets are about 60-90 mm diameter, 4 to 5 T peak field with a field change of about 0.3 T/s and good field quality. The paper will illustrate the organization of the collaboration and the technical pro-gram. Various superconductor options (LTS, MgB2 or HTS) and different magnet shapes, like classical CosTheta or innovative Canted CosTheta (CCT), with curved multifunction (dipole and quadrupole), are under evaluation, CCT being the baseline. These studies should provide design inputs for a new superconducting gan-try design for existing facilities and, on a longer time scale, for a brand-new hadron therapy centre to be placed in the South East Eu-rope (SEEIIST project).
