Description
Targeted α-therapy with α-particle-emitting isotopes such as 225Ac, 223Ra, 213Bi, 212Pb, has demonstrated a successful clinic trial effect. However, the major bottleneck for conducting translational research and future extensive clinical treatments is the limited availability of those α-emitting isotopes. Meanwhile, radioactive ion beam physics research, material irradiation and nuclear micro-porous membrane production demand high intensity heavy ion beams. A compact superconducting cyclotron for high intensity ion beam with a mass-to-charge ratio of 3 is being designed and developed by Institute of Modern Physics (IMP). The first such compact superconducting cyclotron is being designed which is dedicated to high intensity proton beam for 225Ac and 223Ra medical isotope production with extracted proton beam energy 120 MeV and proton beam intensity 0.5-1.0 mA by acceleration of H3+ beam through stripping extraction. The second one will be dedicated to high intensity heavy ion beams with a mass-to-charge ratio of 3 and extracted beam energy 120 MeV/A and typical beam intensity 5 pμA. Perspective and design studies of such high-intensity compact superconducting cyclotrons will be presented in the talk.
