Development and Application of Compact High-current Proton Cyclotron at China Institute of Atomic Energy
Since the establishment of the first cyclotron in China in 1958,the China Institute of Atomic Energy(CIAE)has developed a series of high-current cyclotron devices,playing a crucial role in the development of nuclear science disciplines and applications of nuclear technology in China.In 1996,CIAE completed China's first dedicated 30 MeV/350 μA high-current proton cyclotron for medical isotope production.In 2014,it constructed the world's largest compact 100 MeV/520 μA high-current proton cyclotron large-scale scientific facility.In 2021,CIAE independently developed China's first 14 MeV high-current proton cyclotron with an extraction current exceeding 1 mA.The completion of the 14 MeV/1 mA high-current proton accelerator laid the foundation for the application of neutron source based on miniaturized high-current proton cyclotron in China.Based on the 14 MeV high-current proton cyclotron,CIAE successively established China's first prototype of a boron neutron capture therapy(BNCT)treatment device and an experimental verification prototype for neutron imaging non-destructive testing,and conducted related experimental research.Currently,CIAE is developing an 18 MeV/1 mA high-current proton cyclotron for applications such as BNCT clinical use,and is engaged in the development of a new high-current cyclotron based on H2+with beam currents reaching 3-5 mA.CIAE's high-current cyclotrons will play an important role in applications such as BNCT and neutron imaging based on accelerator neutron sources,and accelerator production of medical radioisotopes.
