Facilities and Technical Applications for Nuclear Physics Accelerator in China Institute of Atomic Energy
摘要
Abstract
China Institute of Atomic Energy(CIAE)has persistently developed technologies including radioactive beam generation,low-energy high-voltage accelerators,tandem accelerators,and high-frequency accelerators.Nuclear physics research facilities,such as the HI-13 Tandem Accelerator,superconducting linear accelerator,multi-particle variable-energy cyclotron,600 kV high-voltage multiplier,high mass resolution on-line isotope separator,and Jinping underground high-current accelerator,has been established.The HI-13 Tandem Accelerator has accumulated nearly 150 000 h of operation with 125 000 h of beam supply.In 2014,it is upgraded to the Beijing Radioactive Ion-beam Facility with a new cyclotron and a new on-line isotope separator upstream and a new superconducting booster downstream.In 2016,a superconducting linear accelerator was being constructed to increasing maximum energy gain to 17 MeV/q instead of the booster.The multi-particle variable-energy cyclotron is an isochronous cyclotron with a maximum acceleration factor K of 130,delivering proton energies up to 72 MeV.The 600 kV high-voltage multiplier runs over 1 500 h annually,completing more than 30 experiments and serving over 30 research institutes and enterprises.The Jinping underground astrophysical experiment facility currently holds the world record for the strongest deep-earth accelerator beam intensity,surpassing Italy's LUNA laboratory accelerator by tenfold.Based on the Beijing Radioactive Ion-beam Facility,the calcium oxide,magnesium oxide,silicon carbide,lanthanum carbide,and uranium carbide targets were developed in recent years.By utilizing an innovative dual-mode ion source structure,it has generated 55 types of radioactive isotope beams including sodium,potassium,aluminum,and rubidium,with the shortest half-life reaching 0.17 s and maximum beam intensity at 1010 s-1,achieving international advanced levels.CIAE has developed industrial projects such as small tandem accelerators,small neutron generators,accelerator mass spectrometer,and nuclear pore membrane production based on nuclear physics accelerator technology.In 2025,a 2×1.7 MV and a 2×3 MV tandem accelerators were delivered to users,and in 2026,a 2×6 MV tandem accelerator will be delivered,product standardization is preliminarily completed and technical self-reliance is achieved.CIAE has developed compact neutron generators and time-marking neutron generators with accuracy better than 1 ns and position-marking accuracy better than 0.3 mm.A high-flux neutron generator with capable of producing 3×1012 neutrons per second is under research.CIAE has developed atmospheric-insulated mass spectrometers and compact mass spectrometers,and has established an accelerator-based nuclear pore membrane production line,providing various nuclear pore membrane products.关键词
