3. Ionization Cooling Ionization cooling is crucial technique for muon colliders and neutrino factories –Only way to cool a muon beam before it decays –Only way to achieve high enough collider luminosity or neutrino flux Y. Torun, IIT | All Experimenters' Meeting (FNAL, April 1, 2013)3

4. MICE Deliverables MICE Goals –Demonstrate feasibility and performance of muon ionization cooling by building and testing actual sections of cooling channels –Validate Monte Carlo models –Understand performance well enough to reliably extrapolate cost of muon cooling channels for MC or NF Measurement of ≈10% emittance reduction to 1% relative precision, i.e., 10 –3 emittance resolution Requires particle-by-particle measurements MICE Step IV: –Demonstration of ionization cooling of muons, but without re- acceleration (i.e., “non-sustainable” cooling) –Precision measurements of absorber effects on beam validate our simulation models MICE Step VI: –Demonstrate sustainable cooling, with RF re-acceleration –Full exploration of lattice optics and detailed validation of simulations Y.

10. Conclusion MICE is a program to demonstrate that ionization cooling is feasible and well understood Will demonstrate the principles of 6- dimensional cooling as well as transverse …and thus lay the groundwork for muon colliders and neutrino factories …by 2019 if all goes well Progressing towards 1 st (Step IV) data in 2014/15 Y.
