Design and Test Results of the FRIB Superconducting Focusing Magnet
摘要
Facility for Rare Isotope Beams (FRIB) is a scientific user facility for the U.S. Department of Energy Office of Science (DOE-SC), supporting the mission of the DOE-SC Office of Nuclear Physics, and Michigan State University is home to FRIB. The superconducting magnet is used for focusing and steering the heavy ion beams for FRIB driver linac. The magnet is made of NbTi wire, and cooled by liquid helium. The testing results show that all the 81 sets of the FRIB magnet achieved 100% of the calculated current value of 90 A, and the peak field on beam axis is 8.0 T.
