Despite the issues with DUNE, P5 recommended initiating work on a new megaproject called a muon collider. Accelerating and colliding muons for particle physics studies offers theoretical advantages over an electron-positron collider, but represents an untested and challenging new direction from a practical standpoint. The report states: “Although we do not know if a muon collider is ultimately feasible, the road toward it leads from current Fermilab strengths and capabilities to a series of proton beam improvements and neutrino beam facilities, each producing world-class science while performing critical R&D towards a muon collider. At the end of the path is an unparalleled global facility on US soil. This is our Muon Shot.” The cost of a 10 TeV muon collider was not estimated in the report.
