Cold Powering Tests of 11-T Nb$_{3}$Sn Dipole Models for LHC Upgrades at CERN

For the upgrade of the LHC in LS2 and for the High Luminosity upgrade in LS3, a few 15-m Nb-Ti main dipole magnets are foreseen to be replaced by two 5.5-m-long Nb$_{3}$Sn dipoles each. After a series of dipole models produced and tested by the collaborating partners at FNAL, in 2014 and 2015, the f...

Descripción
Sumario:For the upgrade of the LHC in LS2 and for the High Luminosity upgrade in LS3, a few 15-m Nb-Ti main dipole magnets are foreseen to be replaced by two 5.5-m-long Nb$_{3}$Sn dipoles each. After a series of dipole models produced and tested by the collaborating partners at FNAL, in 2014 and 2015, the first short dipole model magnets have been produced and tested at CERN in a single aperture configuration. In this paper, the test results and test analyses will be discussed with a focus on training and cold powering performance.
