Description
The cyclotron, which has been around for over 80 years, experienced a period of vigorous development in the last ten years due to urgent needs in multiple application fields, specially for ultra-compact, ultra-lightweight, and high-power cyclotrons.
Since 2013, a low-temperature 230MeV superconducting cyclotron CYCIAE-230 has been developed and successfully obtained the first beam at 231MeV in 2020, which is the first SC cyclotron in China. Currently, CYCIAE-230 has commenced industrialization in Chengdu, China, for proton therapy of cancer and proton irradiation of aerospace chips. Since 2019, a 100MeV high-temperature SC cyclotron CYCIAE-100B has been designed and is under construction now, which is the first try for iron-less, ultra-lightweight cyclotron development. In addition, CIAE started recently an ultra-compact, multi-particle (charge-to-mass ratio of 1:2) SC cyclotron project CYCIAE-36A, for accelerating α and H2+ beam. It will be used for production of 211At, the study of the effects of α irradiation on new materials and aerospace biological effects, and the large-scale production and stable supply of commonly used PET isotopes. Finally, we have been continuously optimizing the design of a 2GeV high-power, high-energy efficiency isochronous FFA proton accelerator CYCIAE-2000, and have been conducting necessary key technical research and engineering design verification, including the 1:4 FDF magnet based on high-temperature superconducting technology.
