  Colliders are built on a foundation of superconducting magnet technology that
provides strong dipole magnets to maintain the beam orbit and strong focusing
magnets to enable the extraordinary luminosity required to probe physics at the
energy frontier. The dipole magnet strength plays a critical role in dictating
the energy reach of a collider, and the superconducting magnets are arguably
the dominant cost driver for future collider facilities. As the community
considers opportunities to explore new energy frontiers, the importance of
advanced magnet technology - both in terms of magnet performance and in the
magnet technology's potential for cost reduction - is evident, as the
technology status is essential for informed decisions on targets for physics
reach and facility feasibility.
