Low Emittance Muon Collider
Rolland Johnson
Muons Inc.

Many new ideas for muon beam cooling have improved the prospects for an energy-frontier muon collider. Cooling to normalized transverse emittances of a few mm-mr and using effective emittance exchange to reduce momentum spread allows high luminosity with fewer muons than previously imagined as well as the possibility to use high-frequency RF. A proton driver linac using TESLA style cavities can perform double duty to produce the muons and then to accelerate them to the energy of a neutrino factory. The muons can then be coalesced, injected into a recirculating ILC linac, accelerated to high energy, and brought into collision in a Tevatron-sized ring. The Low Emittance Muon Collider Workshop ( has the goal of synthesizing new and older cooling ideas to achieve a plausible design of a 5 TeV muon collider with an average luminosity of 10^35, and to come up with an implementation plan that includes a superior neutrino factory as an intermediate step.
