The next generation particle accelerators will need to increase by an order of magnitude the center-of-mass energy: a viable solution is a 100 TeV circular collider, temporarily called Future Circular Collider (FCC). To achieve this goal, a new generation of double aperture superconducting magnets, capable of generating a high quality, stable 16 T magnetic field in a 50 mm bore is being developed. [...]

The Falcon Dipole (Future Accelerator post-LHC Cos-theta Optimized $\rm {Nb_3Sn}$ Dipole) is a single aperture $\rm {Nb_3Sn}$cos-theta dipole short model in the framework of the Future Circular Collider (FCC) project. The Italian Institute of Nuclear Physics (INFN), in collaboration with CERN, is in charge of designing and constructing the magnet, which is a crucial step towards the construction of High Field $\rm {Nb_3Sn}$magnets suitable for a post LHC collider.

Impact of betatron collimation losses in the High-Energy Large Hadron Collider
/ Varasteh, M (CERN) ; Bruce, R (CERN) ; Cerutti, F (CERN) ; Crouch, M (CERN) ; Zimmermann, F (CERN)
In response to recommendations in the 2013 update of the European Strategy for Particle Physics, a conceptual design effort for an energy upgrade of the Large Hadron Collider (LHC) at CERN, the so-called high-energy LHC (HE-LHC), was launched as part of the Future Circular Collider study. The HE-LHC machine, which is meant to use 16 T magnet technologies in the existing LHC tunnel, would provide proton collisions at a center-of-mass energy of 27 TeV (∼2×LHC) with a total stored energy of 1.34 GJ (∼4×LHC) per beam.

Length Changes of Unconfined Nb$_3$Sn Rutherford Cables During Reaction Heat Treatment
/ Michels, Matthias (CERN) ; Lackner, Friedrich (CERN) ; Scheuerlein, Christian (CERN) ; Carlon Zurita, Alejandro (CERN) ; Ferradas Troitino, Salvador (CERN) ; Bourcey, Nicolas (CERN) ; Savary, Frederic (CERN) ; Tommasini, Davide (CERN)
In order to predict volume changes of Nb3Sn coils during reaction heat treatment (RHT), coefficients of thermal expansion (CTE) of the involved materials need to be known. While the CTEs of bulk materials are widely available, there is a lack of knowledge about the dimensional changes of the Nb3Sn Rutherford cables. [...]

Quantitative Analysis and Optimization of Nb$_3$Sn Wire Designs Toward Future Circular Collider Performance Targets
/ Hopkins, Simon C (CERN) ; Baskys, Algirdas (CERN) ; Valero, Adrià Canós (CERN) ; Ballarino, Amalia (CERN)
In the context of the Future Circular Collider (FCC) study, industrial and academic partners are developing novel Nb3Sn superconducting wires with a wide variety of layouts, production methods, and compositions, with the aim of achieving challenging performance targets including a non-copper critical current density of 1500 A mm-2at 16 T and 4.2 K. There is a clear need for a systematic and quantitative approach to analyze these conductors, identifying correlations between performance, microstructure, and wire design, in order to optimize designs and heat treatments, and to identify the most promising directions for future trials.

In the framework of a design study for a post-LHC 100 TeV circular hadron collider, namely FCC-hh, high-gradient Nb$_3$Sn lattice quadrupoles were investigated, following closely the specifications from the optic layout of that machine. After several iterations, a baseline design of the main quadrupole was selected and, then, included in the FCC-hh Conceptual Design Report. [...]

The enhanced racetrack model coil and racetrack model magnet constitute the current R&D; Nb$_3$Sn magnets under development at CERN aiming to achieve dipole fields of 16-18 T, the design baseline of the Future Circular Collider (FCC). This article reports the mechanical behavior of their common support structure, which underwent three different levels of room-temperature preload (with the bladders and key method) and two cooldown cycles to 80 K.
