MICE CM16 Goals Alain Blondel 8 October Competition is active! better beta beams: use higher Q isotopes (C.Rubbia) instead of He or Ne (Q~3 MeV) 8 B --> 8 Be e + e or 8 Li --> 8 Be e - anti- e + New production scheme would allow higher intensities --> altogether higher energy and higher rates for the same storage ring rigidity

MICE CM16 Goals Alain Blondel 8 October this minimal 3 family picture plots and similar plots within and beyond the minimal picture will continue to be refined and clarified as progress is made by proponents of the various options CHOICE will depend on --   --cost --timescale PRELIMINARY

MICE CM16 Goals Alain Blondel 8 October ISS--> IDS aspirational time line: ISS report: end of 2006 will include a description of the R&D and ressources necessary to produce InterimDesignReport in 2010 and CDR in 2012 Next « ISS » meeting second half of february CERN preparation of funding proposals Review of where we stand at NUFACT07 mid-2008 (NUFACT08) funded engineering phase begins 2010 IDS interim report 2012 CDR Meanwhile a European Oversight Committee should be put in place to coordinate neutrino-beam requests.

MICE CM16 Goals Alain Blondel 8 October Regional Oversight Committees Nufact study Accelerator Detectors Physics Betabeam study Accelerator Detectors Physics Superbeam study (or studies) Accelerator Detectors Physics Neutrino Oscillation Physics Working Group -- exact structure of each study to be decided by proponents -- Regional Oversight Committees will possibly converge to a single international committee for a future precision neutrino facility

MICE CM16 Goals Alain Blondel 8 October EP2010: « pursue an internationally coordinated, staged program in neutrino physics » CERN-SG: Studies of the scientific case for future neutrino facilities and the R&D into associated technologies are required to be in a position to define the optimal neutrino programme based on the information available in around 2012 ; Council will play an active role in promoting a coordinated European participation in a global neutrino programme. Towards a high-intensity neutrino programme

MICE CM16 Goals Alain Blondel 8 October  Aspirational MICE Schedule now (date= ready to take data) 15 September 2007 NB: picture does not include target, beam line, hall infrastructure, electronics, DAQ, shifters etc… ! STEP I November 2007 STEP III: Winter 2008 STEP II STEP IV Fall 2008 STEP V Spring 2009 STEP VI Fall 2009

MICE CM16 Goals Alain Blondel 8 October STEP I: 15 September 2007 = 340 days to data taking! STEP II: soon after PHASE I  MAIN GOAL of meeting: Understand where we stand in our preparations for Steps I and II (and III). More Generally: monitor status of experiment, make necessary decisions to move forward, identify issues that require action

MICE CM16 Goals Alain Blondel 8 October EXPECTED RESULTS --I-- (from CM15 to CM16) BEAM LINE -- target system: solution for heating of linear mechanism, test of system progress of first beam test (expected end of october 2006) -- status of beam solenoid -- beam line construction -- optics: full coverage of emittances and momenta? correction and tuning systems; collimators and controls -- diffuser size & mechanism

MICE CM16 Goals Alain Blondel 8 October EXPECTED RESULTS --II-- (from CM15 to CM16) DETECTORS -- results of test beams at Frascati and Fermilab -- upstream Cherenkov and TOF0/1 review at the end of the meeting -- tracker (first plane and QA?) -- downstream shield/TOF2/EMcal size! -- scraping issue -- funding and schedule issue! DAQ and controls -- workshop in Daresbury in September -- overview of system and proposal

MICE CM16 Goals Alain Blondel 8 October TOF Ennoying questions: TOF2 said to be mid Can this be brought forward? what will happen with x-ray radiation when we run with RF? Issue: particles crossing material in the downstream end of the spectrometer this is a beam of MeV/c, all generated with 4T field in spectrometer. How about the size of the hole in the shielding Preparations of TOF0 test on-going (Milano-Pavia) double layer allows measurement of resolution, meast is of this is the main aim of the test

MICE CM16 Goals Alain Blondel 8 October EXPECTED RESULTS --III-- (from CM15 to CM16) ANALYSIS -- run plan (time is expensive and people are few) -- time measurement discussion -- scraping, emittance propagation etc.. -- associated questions: time definition in MICE (master clock?) SOFTWARE -- launching MICE data Challenge? -- continuous improvements (last time was spectacular)

MICE CM16 Goals Alain Blondel 8 October EXPECTED RESULTS --IV-- (from CM15 to CM16) INFRASTRUCTURE -- general experiment infrastructure -- MICE-folks becoming official users at RAL -- HAZOP and safety report PHASE 2 -- UK bid under review -- LH2 R&D -- Coupling coil (First Harbin report in a collaboration meeting!) -- RF cavity progress at Fermilab -- power source progress -- RFCC and absorbers PHASE 3 -- how does MANX match to MICE?

MICE CM16 Goals Alain Blondel 8 October PERSONNEL (will be proposed to Collab. Board) Y. Torun has a new job (congratulations) -- VC planner K. Long --> JS. Graulich -- ANALYSIS Forum Y. Torun --> J. Cobb (TBC)
