1. NEWS • CERN’s SPSC at Villars: recommandations • MICE step 2.5 • Upcoming gateway steps • RF from LBNL (Mike) • Collaboration meeting (Paul) • Others?

3. m - STEP I: spring 2006 STEP II: summer 2006 STEP III: winter 2007 STEP IV: spring 2007 STEP V: fall 2007 STEP VI: 2008

4. Critical path items at the start are clearly a) the beam and b) the spectrometer solenoid (2->2.5 years after order) Funding to get the spectrometer solenoids is difficult and causes delay. (~2 M€ a pair of rather standard technology) the MICE management proposes to deal with this potential stumbling block, while remaining committed to ultimately achieving the full goals of MICE (“Step VI” above) by proceeding with additional intermediate steps boundary condition: additionalintermediate steps use mainly items that are part of the final MICE configuration. The soonest we may be able to get the firstspectrometer is from US funding This leads to the consideration of step II.V (2.5)

5. Establish beam match and wether we have all knobs necessary to draw Emittance vs transmission curve. Measure emittance m - STEP I STEP II Split tracker in two parts and measure against each other (systematics) STEP II.V Insert absorber (solid) between the two halves and measure Pt & E distribution and emittance growth STEP II.VI These are mostly questions for beam design and matching to and within solenoid.

6. the MICE collaboration is confident that it has enough resources to go ahead with practical measurements and achieve a first worthwhile goal. •  justify our request to proceed with the implementation of the muon beam line. • U.S. decision on Step 2.5 funding might be possible in about six months. • Meanwhile we are actively pursuing the following alleys that should get us further • letter of intent submitted to Italian funding agency to proceed • towards a full proposal to INFN; (under review now) • Investigations on use of MRI magnets that could be borrowed or lent • from company to be used as spectro. magnets, at least temporarily. • We are exploring a request to the EU funding programmes for MICE • under the heading “NEST” (New and Emerging Science and Technology). • If any of this materializes soon enough US funding could be redirected towards RFCC • Module, maybe in a reduced version (MICE step V.0 ?) well along full MICE, • since AFCC module funding (UK &Japan) is earmarked (though not released) • A note on this is being prepared for discussion at the MICE collaboration board in RAL.

7. m - STEP I STEP II STEP III STEP IV This may be too expensive… Although we do have good prospect to secure 8 MW of RF power. STEP V

8. STEP V STEP V.0 Shorter, less expensive, no coupling coil, (very limited optics flexibility) does this work in flip, RFoFo, non flip modes? These are mostly optics questions

9. Upcoming gateway steps -- the foreseen cost and schedule review is foreseen on November 12th Essential ingredient for this : our beautiful Technical Design Report http://www.isis.rl.ac.uk/accelerator/mice/tr/mice_tech_ref.html -- gateway 2/3 will be separated for i) Beam Line and ii) MICE proper. revue for Beam line expected in late december. The discussion of step 2.5 above is quite relevant for this!
