英文摘要	To solve the problems of huge magnet weight and expensive operation of Gantry therapy device, this paper proposes a new type of coil structure based on tilted solenoids. We have completed a 2.5 T NbTi superconducting magnet prototype design for heavy ion Gantry, which effectively reduces the gantry's size and weight of the magnet compared to the proton therapy. The magnet consists of 10 layers of tilted solenoids with operating current of 1000 A. The coil clear bore is 176 mm in diameter and the good field region can be up to 2/3 of the aperture. Because of the magnet's special shape, it doesn't require optimization and higher order harmonics naturally integrate to zero through the ends. To ensure safe and stable operation of the magnet in the case of rotation, it uses the conduction cooling form. Starting from the concept of tilted solenoid coil, the magnetic field design is reported in detail. Based on ANSYS thermal FEM software, we simulate the temperature profiles inside the magnet and the thermal shield and obtain the thermal distribution of magnet cryogenic system. Finally, we give a brief introduction about the magnet processing.
