FABRICATION AND TEST OF A 1 M LONG SINGLE-APERTURE 11 T NB_3SN DIPOLE FOR LHC UPGRADES

摘要

FNAL and CERN are carrying out a joint R&D program with the goal of building a 5.5-m long twin-aperture Nb_3Sn dipole prototype suitable for installation in the LHC. An important part of the program is the development and test of a series of short single-aperture demonstration dipoles with a nominal field of 11 T at the LHC nominal current of 11.85 kA and 20% margin. This paper describes design features and test results of a 1 m long single-aperture Nb_3Sn demonstrator dipole.
