Measurements of Dynamic Effects in FNAL 11 T Nb3Sn Dipole Models
- Fermi National Accelerator Lab. (FNAL), Batavia, IL (United States)
Fermilab, in collaboration with CERN, has developed a twin-aperture 11 T Nb3Sn dipole suitable for the high-luminosity LHC upgrade. During 2012-2014, a 2-m long single-aperture dipole demonstrator and three 1-m long single-aperture dipole models were fabricated by FNAL and tested at its Vertical Magnet Test Facility. Collared coils from two of the 1-m long models were then used to assemble the first twin-aperture dipole demonstrator. This magnet had extensive testing in 2015-2016, including quench performance, quench protection, and field quality studies. Here, this paper reports the results of measurements of persistent current effects in the single-aperture and twin-aperture 11 T Nb3Sn dipoles and compares them with similar measurements in previous NbTi magnets
