Medical superconducting cyclotron mainly consists of ion source, magnet system, radio frequency system, extraction system, beam diagnostic system and auxiliary systems. The cyclotron employs superconducting technology, with a diameter of only 3 meters and weighing no more than 75 tons. It can produce ~240 MeV beam energy with over hundreds of nano-ampere beam intensity, ensuring highly efficient dose delivery. The cyclotron, based on the physical properties of the “Bragg peak” of the proton, enables static spot scanning, achieving precise radiotherapy.

The 30 MeV Multiparticle Cyclotron is a multi-particle variable energy cyclotron capable of providing both proton and α particles. By accelerating H- ions and combining them with a stripping extraction method, it can produce proton beams with energies ranging from 18 to 30 MeV. This not only enables the production of isotopes such as 18F, 67Cu, 225Ac, and 124I but also meets a broader range of isotope production needs, including 68Ge, 111In, 201Tl, and 123I. Additionally, by accelerating α particles and using an electrostatic deflection extraction method, it can produce 30 MeV α particles, which are used for the production of the isotope 211At for α-targeted therapy. The cyclotron can meet the demands for conventional isotope production and the production of next-generation radioactive isotopes.
