Quench Performance of the First Twin-aperture 11 T Dipole for LHC upgrades

FNAL and CERN are developing a twin-aperture 11 T Nb$_{3}$Sn dipole suitable for installation in the LHC. A single-aperture 2-m long dipole demonstrator and two 1-m long dipole models have been fabricated and tested at FNAL in 2012-2014. The two 1 m long collared coils were then assembled into the f...

description FNAL and CERN are developing a twin-aperture 11 T Nb$_{3}$Sn dipole suitable for installation in the LHC. A single-aperture 2-m long dipole demonstrator and two 1-m long dipole models have been fabricated and tested at FNAL in 2012-2014. The two 1 m long collared coils were then assembled into the first twin-aperture Nb$_{3}$Sn demonstrator dipole and tested. Test results of this twin-aperture Nb$_{3}$Sn dipole model are reported and discussed.

A single-aperture 2-m long dipole demonstrator and two 1-m long dipole models have been fabricated and tested at FNAL in 2012-2014. The two 1 m long collared coils were then assembled into the first twin-aperture Nb$_{3}$Sn demonstrator dipole and tested. Test results of this twin-aperture Nb$_{3}$Sn dipole model are reported and discussed.The LHC luminosity upgrade plan foresees installation of additional collimators in Dispersion Suppressor areas around point 7 and interaction regions 1, 2 and 5. The required space for these collimators could be provided by replacing some 15-m long 8.33 T NbTi LHC main dipoles (MB) with shorter 11 T Nb$_{3}$Sn dipoles (MBH) compatible with the LHC lattice and main systems. FNAL and CERN magnet groups are developing a 5.5-m long twin-aperture dipole prototype with the nominal field of 11 T at the LHC nominal current of 11.85 kA suitable for installation in the LHC. Two of these magnets with a collimator in between will replace one MB dipole. The single-aperture 2-m long dipole demonstrator and two 1-m long dipole models have been assembled and tested at FNAL in 2012-2014. The 1 m long collared coils were then assembled into the first twin-aperture Nb$_{3}$Sn demonstrator dipole and tested. This paper reports test results of the first twin-aperture Nb$_{3}$Sn dipole model focusing on magnet training, ramp rate sensitivity and temperature dependence of the magnet quench current. The twin-aperture dipole quench performance is compared with the data for the single-aperture models.FERMILAB-CONF-15-178-TDoai:inspirehep.net:14060642015
