Input to the SCAC Facilities Subcommittee from the U.S. Muon Collider Collaboration

Abstract: This document presents input from the U.S. Muon Collider Collaboration to the SCAC Facilities Subcommittee. It outlines the scientific motivation for a future Muon Collider, the R&D and demonstration program needed to establish its feasibility, and its relevance to U.S. facilities planning for 2026-2036. It also discusses opportunities for leveraging existing U.S. capabilities, developing the accelerator workforce, and building synergies with other DOE programs and international efforts.
