Tumour treatments with high velocity ion beams or protons are characterised by a great depth precision (Bragg pic) and a low divergence for dose delivery in very small volumes. In order to spare normal tissues before and around the tumour it is necessary to have the choice of the beam incidence because the patient cannot be moved. Different devices have been built mainly exocentric and isocentric. Many others are being studied. Cryogenic solutions are analysed to reduce the total mass in rotation. For example it would be very interesting to choose a superconductive solution for the last 90° dipole.
