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. [...]

The 16 T Dipole Development Program for FCC

Abstract:
A key challenge for a future circular collider (FCC) with centre-of-mass energy of 100 TeV and a circumference in the range of 100 km is the development of high-field superconducting accelerator magnets, capable of providing a 16 T dipolar field of accelerator quality in a 50 mm aperture. This paper summarizes the strategy and actions being undertaken in the framework of the FCC 16 T Magnet Technology Program and the Work Package 5 of the EuroCirCol..

Geometrical Behavior of Nb$_{3}$Sn Rutherford Cables During Heat Treatment
/ Durante, Maria (Saclay) ; Garcia Fajardo, Laura (CERN) ; Ferracin, Paolo (CERN) ; Manil, Pierre (Saclay) ; Perez, Juan Carlos (CERN) ; Rifflet, Jean-Michel (Saclay) ; Rondeaux, Francoise (Saclay)
In Nb$_{3}$Sn accelerator magnets, non-superconducting precursor cables are wound into their final coil shape and then heat treated at a high temperature to form the A15 superconducting phase. The growth of cable strands during reaction and the differential thermal dilatation in the coil components lead to both stress in the cable and geometrical deformations of the winding, with possible consequences on magnet performances [...]
