  1. Status of the Muon Ionization Cooling Experiment (MICE) Yagmur Torun Illinois Institute of Technology April 1, 2013

  2. Outline MICE Y. Torun, IIT | All Experimenters' Meeting (FNAL, April 1, 2013) Intro and Goals Scope & Timeline Recent Progress Management Team Institutions, personnel, & management Conclusion

  3. Ionization Cooling Y. Torun, IIT | All Experimenters' Meeting (FNAL, April 1, 2013) • 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 enoughcollider luminosity or neutrino flux

  4. MICE Deliverables MICE Steps Y. Torun, IIT | All Experimenters' Meeting (FNAL, April 1, 2013) • MICE Goals • Demonstrate feasibility and performance of muon ionizationcooling by building and testing actual sections of cooling channels • Validate Monte Carlo models • Understand performance wellenough to reliably extrapolate cost of muoncooling channels for MC or NF • Measurement of ≈10% emittance reduction to 1% relative precision, i.e., 10–3emittanceresolution • 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

  5. Scope of US MICE Effort Y. Torun, IIT | All Experimenters' Meeting (FNAL, April 1, 2013) • Detectors (complete) • Two fiber trackers with(NSF MRI) readout & cryogenics • Twoaerogel 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 • Magneticanalysis and stray-field mitigation • Design and engineering of partial return yoke • Participation in MICE operations and analysis

  6. Recent Progress Y. Torun, IIT | All Experimenters' Meeting (FNAL, April 1, 2013) 1st Spectrometer Solenoid successfully commissioned Solenoid Test Facilityconstruction completed 1st Coupling Coil coldmass delivered toFermilab for testing

  10. Conclusion Y. Torun, IIT | All Experimenters' Meeting (FNAL, April 1, 2013) 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 muoncolliders and neutrino factories …by 2019 if all goes well Progressing towards 1st (Step IV) data in 2014/15
