Design of a Common Coil Magnet Using Existing Racetrack Model Coils (RMC)
/ García-Matos, J A (Madrid, CIEMAT ; Madrid, Escuela Tec. Sup. Ing. Ind. ; GIFT, Spain) ; Jardim, C Martins (Madrid, CIEMAT) ; Toral, F (Madrid, CIEMAT) ; Bermudez, S Izquierdo (CERN) ; Perez, J C (CERN)
The common coil configuration was one of the layouts studied as a candidate to build the required high-field magnets for future colliders, specifically FCC-hh at CERN. The design of the structure to support the large electromagnetic forces and the protection system have been identified as the main challenges. [...]

Construction and Test of the Enhanced Racetrack Model Coil, First CERN R&D; Magnet for the FCC
/ Perez, J C (CERN) ; Bajko, M (CERN) ; Bourcey, N (CERN) ; Bordini, B (CERN) ; Bottura, L (CERN) ; Troitiño, S Ferradás (CERN) ; Gautheron, E (CERN) ; Guinchard, M (CERN) ; Bermudez, S Izquierdo (CERN) ; Mangearotti, F (CERN) et al.
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. [...]

The HL-LHC interaction region magnet triplets (Q1,Q2, and Q3) will be composed of superconducting Nb3Sn quadru-poles. The MQXF quadrupole protection system is based on CLIQ (Coupling-Loss Induced Quench system) and outer layer quench heaters.This paper reports a summary of quench heaters to coil high voltage tests performed on MQXF short and long coils in air after fabrication, and in air and He gas after magnet training.
