For the High Luminosity Upgrade of the CERN Large Hadron Collider, lower $\beta$* quadrupole magnets based on advanced Nb3Sn conductors will be installed on each side of the ATLAS and CMS experiment insertion zones. As part of the technological developments needed to achieve the required field gradient of 132.6 T/m within a 150-mm aperture, short length model magnets, named MQXFS, are tested both at the CERN SM18 and FERMI Lab test facilities.

For the upgrade of the LHC, two 15-m NbTi main dipole magnets are foreseen to be replaced by two 11 T 5.7-m-long Nb$_{3}$Sn dipoles each. A series of model magnets has been produced to verify the design choices that are important for the prototype and series production, focusing on mechanical aspects and protection studies. [...]

Towards an Optimized Coupling-loss Induced Quench Protection System (CLIQ) for Quadrupole Magnets
/ Ravaioli, Emmanuele (CERN ; Twente U., Enschede) ; Datskov, Vladimir I (CERN) ; Desbiolles, Vincent (CERN) ; Feuvrier, Jerome (CERN) ; Kirby, Glyn (CERN) ; Maciejewski, Michal (CERN ; Lodz, Tech. U.) ; Sperin, Kevin A (CERN ; Birmingham U.) ; ten Kate, Herman H J (CERN ; Twente U., Enschede) ; Verweij, Arjan P (CERN) ; Willering, Gerard (CERN)
The recently developed Coupling-Loss-Induced Quench (CLIQ) protection system is a new method for initiating a fast and voluminous transition to the normal state for protecting high energy density superconducting magnets. Its simple and robust electrical design, its lower failure rate, and its more efficient energy deposition mechanism make CLIQ often preferable to other conventional quench protection methods. [...]
