SIS 300 Fast-Cycling Superconducting Quadrupole Prototype

FAIR (Facility for Antiproton and Ion Research), planned to be built at the site of GSI Darmstadt will include the 300 Tm fast-cycling heavy ion synchrotron SIS 300. In the frame of collaboration in FAIR project IHEP developed, produced and tested a prototype of SIS 300 fast cycling superconducting quadrupole. The main parameters of the quadrupole are 45 T/m central gradient, the gradient ramp rate of 10 T/m/s, the useful aperture of 105 mm, the coil inner diameter of 125 mm, 1 m length of the magnet. The one layer coil of the quadrupole is divided by three blocks and was wound by cored cable with 19 strands. The paper presents main characteristics of the magnet and results of its production and test.
