HL-LHC IT STRING: Status and Perspectives
/ Bajko, M (CERN) ; Baglin, V (CERN) ; Ballarino, A (CERN) ; Bednarek, M J (CERN) ; Bertolasi, S (CERN) ; Bertone, C (CERN) ; Blanchard, S (CERN) ; Bozzini, D (CERN) ; Coulot, E (CERN) ; Coupat, C (CERN) et al.
The HL-LHC IT STRING, an integrated test stand for the major components of the HL-LHC Inner Triplet (IT) zone, is in its construction phase in a surface building at CERN. The main motivation is to study and validate the collective behavior of the different systems: magnets, circuit protection, cryogenics for magnets and superconducting link, magnet powering, vacuum, alignment, and interconnections between magnets and superconducting link.

Quench propagation velocity and hot spot temperature models in Nb$_{3}$Sn racetrack coils
/ Lorenzo, Jose (Madrid, CIEMAT) ; Bajas, Hugues (CERN) ; Bajko, Marta (CERN) ; Perez, Juan Carlos (CERN) ; Chiuchiolo, Antonella (CERN)
Since 2010 to present, several subsize magnet assemblies, designed as test beds for the validation of impregnated Nb$_{3}$Sn-based coil technology, have been tested at the Superconducting Magnet Test Facility (SM18) at CERN. These short model coils and racetrack model coils have been used to study two types of Rutherford cables foreseen for the coils of the Nb$_{3}$Sn magnets in the framework of the HL-LHC upgrade and High Field Magnet program of CERN.

/LARP
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.

Racetrack model coils (RMC) have been built at CERN during the past decade, as an R&D; tool to qualify conductors and technologies developed for high field superconducting accelerator magnets (Perez
et al.
, 2016). RMC, assembled in a dipole magnet configuration, proved to be an efficient instrument reducing cost and feed-back time while developing new magnets. [...]

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. [...]
