MICE: challenges, organization,

global funding situation.


Why MICE?

Based on Muon collider ideas and development (Palmer et al, 92->), the Neutrino Factory concept (Geer, 1998) resonated in 1998 with the final demonstration of Atmospheric Neutrino Oscillations by the SuperK Collaboration.

International workshops:NUFACT 99 (Lyon, France)NUFACT 00 (Montery, California) NUFACT 01 (Tsukuba, Japan)NUFACT 02 (London, UK)NUFACT 03 (Columbia,NY,USA)NUFACT 04 (Osaka, Japan)NUFACT 05 (Frascati,Italy)

Neutrino Factoryis the ultimate tool for study of Neutrino Oscillations-- unique source of high energy e

Particle physicist: Q: Can a Neutrino Factory be built?

Accelerator physisicst: A: YES! (US Study II, CERN)

but… it is expensive, and many ingredients have never been demonstrated!

R&D is needed. (est. 5yrs) to 1. ascertain performance2. reduce costs

among critical items:

***Target***

*** COOLING ***

Cooling component development programme MUCOOL collabration (US-Japan-UK)

*** Acceleration ***


IONIZATION COOLING

principle:

this will surely work..!

Difficulty: affordable prototype of cooling section only cools beam by 10%, while standard emittance measurements barely achieve this precision.Solution: measure the beam particle-by-particle

A delicate technology and integration problem Need to build a realistic prototype and verify that it works (i.e. cools a beam)

Can it be built? What performance can one get?

state-of-the-art particle physics instrumentation will test state-of-the-art accelerator technology.

Aims: demonstrate feasibility and performance of a section of cooling channel

Main challenges:RF in magnetic field!10-3 meas. of emittanceSafety issues

Some prototyping:


Challenges of MICE: (these things have never been done before)

1. Operate RF cavities of relatively low frequency (201 MHz) at high gradient (16 MV/m) in highly inhomogeneous magnetic fields (1-3 T)

dark currents (can heat up LH2), breakdowns

2. Hydrogen safety (substantial amounts of LH2 in vicinity of RF cavities)

3. Emittance measurement to relative precision of 10-3 in environment of RF bkg

requires low mass and precise tracker low multiple scattering redundancy to fight dark-current-induced background excellent immunity to RF noise complete set of PID detectors

And…

4. Obtaining funding for R&D towards a facility that is not (yet) in the plans of a major lab


2010 will be a time of major decisions in particle physics

LHC will be completed first results will appear

ILC first results fromT2Kdouble-CHOOZother reactor expts.might be available.

It will be time for the next step in neutrino physics!

It will be important thatpractical feasibility of ionization cooling be demonstrated.

Recommendations

• CERN should make every reasonable effort to deliverthe approved p.o.t. to CNGS.

• Future neutrino facilities offer great promise for fundamental discoveries. CERN should join the worldeffort in developing technologies for new facilities : Betabeams, Neutrino Factory…wherever they are sited.

• Focus now on enabling CERN to do the best choice by 2010 on future physics programme.

• Explore further synergies with EURISOL

PHASE II


The complete cell of the study II cooling channel is composed of

two RF coupling-coil modules with an absorber-focus pair module in the middleThis corresponds to step VI.

Although ionization cooling could already be observed in step V, several aspects of the system such as -- flip between two modules, longitudinal emittance growth would not be covered fully. The complete MICE project extends to step VI.

THE MICE COLLABORATION140 collaborators


The specificities of MICE:

MICE is a collaboration of accelerator physicists and particle physics experimenters

MICE is international

Hardware responsibilities: collaborators pay for what they provide.

There exist collaborations for specific items:ex: Tracker is a collaboration between UK, US, Japan absorbers are a US-Japan collaboration

There are no collaboration-wide shared expenses as could be found in large experimental collaborations and there is no common ‘bank’.

There will be a common fund but we have not enforced it yet.

A few MOU’s have already been signed -- RF sources from Berkeley -- PSI solenoid

The software, analysis etc… are freely shared items.

The MICE partners: I. UK

MICE-UK (Spokesperson Ken Long, ICL, project manager Paul Drumm, RAL) is composed of the following institutions

CCLRC Rutherford Appleton LaboratoryCCLRC Daresbury LaboratoryUniversity groups:Brunel, Edinburgh, Glasgow, Imperial College London, Liverpool, Oxford,Sheffield

The UK groups have been extremely successful at promoting the Neutrino Factory in the UK. (NUFACT02, UKNF collaboration, etc…) They obtained a grant of 9.7 M£ from OST, PPARC, CCLRC.

Contributions Host experiment, provide project management (Paul Drumm, RAL)for phase I: Infrastructure: target, beam line, experimental hall, supports, controls, control room, etc… R&D to assemble RF power sourcesR&D towards liquid hydrogen, windows, infrastructure and storage system Tracker (in collaboration with US and Japan)

for phase II: Focus coils and absorber module assembly Completion of RF sources and liquid hydrogen system and remaining infrastructure


The MICE partners: I. UK

MICE UK has been fully funded for phase I: 9.7M£ OST + PPARC + CCLRC

Funding request for phase II (GW2/3 est. 3.3 M£) will need to be placed in 2006.

Additional project envisaged: construction of one prototype RF cavity in collaboration between industrial partners CCLRC and university groups.Independent funding opportunity exists.


The MICE partners: II. US

US: The Neutrino Factory and Muon Collider Collaborationfounded in 1998

spokespersons: S. Geer, R.B.Palmer Project Manager: Mike Zisman (also deputy spokesperson of MICE) partners: BNL, Fermilab, LBNL + university groups.

NFMCC has pioneered the concept of MICE and developped, through the MUCOOL program, the critical components. The MICE cooling cell is that of ‘study II’ with engineering improvements

The critical remaining R&D consists in tests of 201 MHz RF cavity in magnetic fields to understand whether the needed RF fields can be reached or what needs to be done to reach them. RF cavity n0 1 is built and arrived at FNAL early september 05, for testing. Initially the tests can be done in the stray field of another magnet, but the real magnet (‘coupling coil’) will be needed for a definitive test.


The MICE partners: II. US (Ctd)

The NFMCC is funded at the level of 3.6 M$/ year by DOEin addition it received for MICE specifically: -- an NSF grant of 100k$ a year for the first three years -- an MRI grant of 750k$ from NSF

The NFMCC DOE funding has to cover -- the personnel for studies, engineering and tests-- travel and other consummables-- the hardware construction for MUCOOL, MICE and the recently approved target experiment at CERN ( nTOF11 a.k.a. MERIT)

The NFMCC collaboration has decided to allocate a significant portion of its funding to MICE


The collaboration has proposed the following budget for MICE and MUCOOL:

This, with the NSF contribution of 750+300k$, has to cover the following hardware contributions to MICE– 2 spectrometer solenoids– 2 RFCC modules (1 for step 5, 2 for step 6) – 1 Cherenkov detector (upstream)– a portion of tracker detector (electronics)– 6 absorber windows (plus spares) Hardware cost of these items for step 5 is 4M$, for step 6 is 5.5M$

However: the funding profile pushes step 3 to oct. 2008 and delays MUCOOLStep 5 is pushed to late 2010. Means need to be found to advance the funding profile.

Osaka UniversityKEK

Responsibilities in MICE

Liquid H2 absorbers (R&D and MICE absorbers) Fiber tracker (R&D, fibers) hosted the fiber tracker beam test.

funding: Japan-US collaboration (100k$ per year)

A grant request for future neutrino beams is being prepared (together with HyperKamiokande R&D) for phase II about 1 OkuYens (~1M$) to be submitted in november 2005.

The Japanese team are strong collaborators in MUCOOL and MICE.

The MICE partners: III. Japan


The MICE partners: IV. Switzerland

PSI: PSI provides a (used) beam solenoid. The cost of a new one would be estimated at ~3MCHF.The solenoid has been prepared and is ready to leave PSI.

Cryogenics to be provided by RAL (UK phase I)

Geneva University: dedicated funding request was refused in 2004. Rolling grant is approved ~80 kCHF/Yr for hardware and consummablesfunding for 1 PhD student and one postdoc is granted.

Responsibility: data acquisition, trigger. There is a possibility that a coupling coil could be built in Switzerland; a bid is being prepared for 1MCHF/3 years. If successful this would bring the MUCOOL or MICE coupling coil earlier in time.

Bulgarian collaboration: Swiss National Foundation has granted a Institutional Partnership and Joint Research Project with Sofia University. Several Bulgarian researchers. Will contribute to TOF and trigger.


The MICE partners: V. Italy-INFN

Initially a large group of experimenters from the HARP collaboration + an accelerator group from Frascati+ an engineering group from Genoa

Contributed substantially to the design of spectrometer solenoids. R&D and design work for the time of flight and calorimeter was carried out.

Bid was submitted in July 2005 for detectors (Time-of-Flight and calorimeter) for about 1M€. (Decision this week)

This is the main missing component of phase I.

Hope is that this first step will be followed by further participation from accelerator physicists in Italy. (Frascati)


The MICE partners: VI. NL-NIKHEF

Amsterdam, Nijmegen

will contribute the magnetic sensors to the experiment. + 1 PhD student.

The MICE partners: VII. Belgium-Louvain

Proof. G. Gregoire has participated actively in MICE and performed the design of the downstream Cherenkov. (value 250 k€, the phototubes would be donated by the Trieste group from the CHOOZ experiment)

GG has now retired and it is not clear that the group will be able to continue.


The MICE partners: VIII. CERN

The CERN working group contributed greately to the present concept of MICE Following budget cuts end 2001 the contribution of CERN was reduced to the following

CERN has earmarked used RF material able to assemble 2RF power sources providing 2MW each (this is enough to power one of the RF modules). This will remain the property of CERN.

A request has been placed to the CERN AB-head for refurbishing this equipement (cost: 170 kCHF)

MICE is CERN recognized experiment RE11.


at this point MICE (PhaseI) is an approved and funded project in 5 countries

-- UK: 9.7M£

-- USA: funding from the NFMCC (DOE baseline scenario 4.125M$) +RF source + NSF grant 300k$ + MRI grant 750k$. -- Japan: US-Japan ~$100k/yr, UK-Japan (travel funds) (+ 1M$ requested)

-- Switzerland: PSI solenoid + Uni-Geneva-NSwissF (80KCHF/yr)+ 1 PDA+1PhDS +CERN RF. -- Netherlands: Mag probes (in production!) + 1 PhDS

+ Proposal submitted in Italy (TOF, Calorimeter)

Summary:


Conclusions

1. The MICE experiment is scientifically approved and recognized internationallyit has structure, charter, project management.

2. The collaboration is making excellent progress in all fronts:simulationsR&Dengineering prototypingconstruction See Paul Drumm’s presentation

3. The funding for phase I is largely there and will be essentially completeif the INFN bid succeeds-- only Cherenkov II would remain a question.

4. The funding for phase II is being prepared. We have a baseline solution for MICE up to step V but it will be late. Work is needed to assure that step VI can be performed in good time for the decision making-year 2010. We will welcome the FAC committee’s help to achieve this important goal!
