1MICE collaboration meeting Alain Blondel 27 – 10 - 2004

Welcome to the 10th MICE collaboration meeting.

1. Global neutrino factory situation2. Possible intermediate steps towards full MICE3. Aims of this meeting4. Assignments

SPSC 2004 Villars Alain Blondel, 24/09/04

Conclusions 1. The Neutrino Factory remains the most powerful tool imagined so far to study neutrino oscillations

Unique: High energy e and etransitions at large has the precisionat small has the sensitivity

2. The complex off ers many other possibilities

3. I t is a step towards muon colliders

4. There are good hopes to reduce the cost significantly thus making it an excellent option for CERN in the years 2011- 2020

5. Regional and International R&D on components and R&D experiments are being performed by an enthusiastic and motivated community (rate of progress is seriously slowed by funding constraints, however)

6. Opportunities exist in Europe: HI proton driver, (SPL@CERN)Target experiment @ CERN Collector development @LAL- CERNMICE @ RAL

That is us

.. Future neutrino f acilities off er great promise f or f undamental discoveries (such as CP violation) in neutrino physics, and a post-LHC construction window may exist f or a f acility to be sited at CERN.

..CERN should arrange a budget and personnel to enhance its participation in f urther developing the physics case and the technologies necessary f or the realization of such f acilities. This would allow CERN to play a significant role in such projects wherever they are sited.

..A high-power proton driver is a main building block of f uture projects,and is therefore required.

..A direct superbeam f rom a 2.2 GeV SPL does not appear to be the most attractive option f or a f uture CERN neutrino experiment as it does not produce a significant advance on T2K.

..We welcome the eff ort, partly f unded by the EU, concerned with the conceptual design of a β-beam. At the same time CERN should support the European neutrino f actory initiative in its conceptual design.

The executive board submitted the following to the collaboration board

- STEP I: spring 2006

STEP II: summer 2006

STEP III: winter 2007

STEP IV: spring 2007

STEP V: fall 2007

STEP VI: 2008

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)

WE ARE STUCK!WE ARE STUCK!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: additional intermediate steps use mainly items that are part of the final MICE configuration.

The soonest we *may* be able to get the first spectrometer is from US funding

This leads to the consideration of step II.V (2.5)

7MICE collaboration meeting Alain Blondel 27 – 10 - 2004

- STEP I

STEP II

STEP II.V

Insert absorber (solid) between the two halves and measure Pt & E distribution and emittance growth Publishable result!

STEP II.VI

Split tracker in two parts and measure against each other(systematics)

Establish beam match andwether we have all knobs necessary to draw Emittance vs transmission curve. Measure emittance

These are mostly questions for beam design and matching to and within solenoid.

8MICE collaboration meeting Alain Blondel 27 – 10 - 2004

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 Meanwhile we are actively pursuing the following alleys that should get us furtherfurther 1. letter of intent submitted to Italian funding agency to proceed towards a full proposal to INFN; (under review now) (spectrometer solenoids!)

2. Investigations on use of MRI magnets that could be borrowed or leased from company to be used temporarily as spectrometer Magnets

3. 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)

This may be too expensive…Although we do have good prospect to secure 8 MW of RF power.

10MICE collaboration meeting Alain Blondel 27 – 10 - 2004

STEP V

STEP V.0

Should get 5-10 MV RF acceleration (limited by dark current) Shorter, less expensive, no coupling coil, (very limited optics flexibility) does this work in flip, RFoFo, non flip modes? These are mostly optics questions

Upcoming UK 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 revue will take place late december (?) and will be focused on Beam Line and MICE design and development

The discussion of step 2.5 above is quite relevant for this!

Congratulations Paul!

12MICE collaboration meeting Alain Blondel 27 – 10 - 2004

Aims for this meeting

Decisions: According to follow up of Osaka CM, we need to achieve this time:

1 cryocooler decision remaining issue was Liq. He use for absorbers should be possible at least occasionally (not routine operation)

2 tracker validation remaining issues were mostly on performance (PL resolution?) rms resolution should be <10% of rms of distribution at eq. emittance. without and with RF background. MICE note has been drafted and given to referrees (Gregoire + Summers)

3 decision on magnetic shielding for detectors upstream and downstream

Also: 4 agree on policy towards step 2.5 & request for spectrometer solenoids (CB)

There are difficulties in funding but there are good hopes that situation will unlock progressively. We dont want to be caught sleeping! Lets go ahead.

13MICE collaboration meeting Alain Blondel 27 – 10 - 2004

Watch Progress (and enjoy if possible)

5 end to end simulation of MICE with G4MICE (RF background)

6. controls and monitoring of physics parameters (are we going anywhere here?)

7. finish matching all steps of MICE (essentially done, Bravo Ulisse) There remain many studies to be made to assess precision of predictions taking into account imperfections etc…. a lot of work for the optics group! (Welcome back Cristina)

+ construction of first RF cavity shipping of RF components to RAL MUCOOL test area first results from TPG Tracker analysis Beam design and simulations, and more.

14MICE collaboration meeting Alain Blondel 27 – 10 - 2004

Assignments:Define path ahead and understand how to get there

Example AFC working group: will define steps ahead to validate Hydrogen system, and delineate raodmap leading to first AFC module. This may include:-- prototyping of hydrogen system or critical parts thereof, incl. monitors-- safety review Similar road maps should be drawn for simulations, optics, RF tests, detector prototyping and beam test, etc..

PAC2005: could all working group conveners discuss and prepare abstracts to be submitted to this big accelerator conference?Lets take advantage of this meeting to get this done.
