A future circular collider (FCC) with a center-of-mass energy of 100 TeV and a circumference of around 100 km, or an energy upgrade of the LHC (HE-LHC) to 27 TeV require bending magnets providing 16 T in a 50-mm aperture. Several development programs for these magnets, based on Nb$_3$Sn technology, are being pursued in Europe and in the U.S. [...]

In the framework of the High-Luminosity Large Hadron Collider, the installation of a new generation of quadrupole magnets is foreseen on each side of ATLAS and CMS experiments. The new magnets are based on Nb$_{3}$Sn technology and shall be able to reach an ultimate current of 17.9 kA with a peak field of 12.3 T in the coil. [...]

As part of the High-Luminosity Large Hadron Collider (LHC) Project, a set of Nb$_{3}$Sn quadrupoles are being developed, aiming to enhance the performance of the inner triplets. The new magnets, identified as MQXFA and MQXFB, will share the same cross section with two different lengths, 4.2 and 7.2 m, respectively. [...]

Status of the 16 T Dipole Development Program for a Future Hadron Collider
/ Tommasini, Davide (CERN) ; Arbelaez, Diego (LBL, Berkeley) ; Auchmann, Bernhard (CERN) ; Bajas, Hugues (CERN) ; Bajko, Marta (CERN) ; Ballarino, Amalia (CERN) ; Barzi, Emanuela (Fermilab) ; Bellomo, Giovanni (INFN, Milan) ; Benedikt, Michael (CERN) ; Izquierdo Bermudez, Susana (CERN) et al.
A next step of energy increase of hadron colliders beyond the LHC requires high-field superconducting magnets capable of providing a dipolar field in the range of 16 T in a 50-mm aperture with accelerator quality. These characteristics could meet the requirements for an upgrade of the LHC to twice the present beam energy or for a 100-TeV center of mass energy future circular collider. [...]

During the development of MQXF, the new Nb$_{3}$Sn quadrupole to be used in the large hadron collider (LHC) inner triplets for the High Luminosity upgrade, three short models were tested: MQXFS1, MQXFS3, and MQXFS5. These models differ in the use of thin or thick laminations for the iron components, in the coil design, and in the superconductive strands, rod restack process (RRP) or powder in tube (PIT). [...]
