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

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
MICE Steps
Y. Torun, IIT | All Experimenters' Meeting (FNAL, April 1, 2013) 5
Scope of US MICE Effort• Detectors (complete)
– Two fiber trackers with (NSF MRI) readout & cryogenics– Two aerogel Cherenkov detectors (NSF MRI)
• Solid Absorbers– LiH disk (complete)– LiH wedges
• Two superconducting spectrometer solenoids• Two large-aperture (1.5m), 2.5T SC solenoids (“Coupling Coils”)
– First will be used in MuCool Test Area for total of 3
• RF System– Eight 201 MHz cavities with tuners and vacuum vessels
• Integrated with CCs
– RF power components (through NSF MRI)• Commercial products
• Magnetic analysis and stray-field mitigation– Design and engineering of partial return yoke
• Participation in MICE operations and analysis

Recent Progress
• 1st Spectrometer Solenoid successfully commissioned
• Solenoid Test Facilityconstruction completed
• 1st Coupling Coil coldmass delivered toFermilab for testing

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 1st (Step IV) data in
2014/15
