Status of the 16 T Dipole Development Program for a Future Hadron Collider

A next step of energy increase of hadron collidersbeyond the LHC requires high-field superconducting magnetscapable 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 centerof massenergy future circular collider. This paper summarizes the activities and plans for the development of these magnets, in particular within the 16 T Magnet Technology Program, the WP5 of the EuroCirCol, and the U.S. Magnet Development Program.
