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

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
