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.

Cooling component development programme+ ‘blast test’:
MUCOOL collabration (US-Japan-UK)
this will surely work..!
Need to build a realistic prototype and verify that it works (i.e. cools a beam)
Difficulties lay in particular in
What performance can one get?
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
state-of-the-art particle physics instrumentation
will test state-of-the-art accelerator technology.
10% cooling of 200 MeV/c muons requires ~ 20 MV of RF
single particle measurements =>
measurement precision can be as good as D ( e out/e in ) = 10-3
never done before either…

(these things have never been done before)
1. Operate RF cavities of relatively low frequency (200 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
4. Obtaining funding for R&D towards a facility that is not (yet) in the plans of a major lab

THE MICE COLLABORATION
MICE is a collaboration of
accelerator physicists and particle physics experimenters
MICE is international
Hardware responsibilities equate committment to provide specific items
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
There exist no common fund or author tax at this point.
Very few MOU’s have been signed so far
-- RF sources from Berkeley
-- PSI solenoid
The software, analysis etc… are freely shared items.

Today is the first MICE Funding Agency Committee
this constitutes an important step in our development.
We expect to report regularly and would like to make sure
that data are reported in the right format.
MICE-UK (Spokesperson Ken Long, ICL) is composed of the following institutions
CCLRC Rutherford Appleton Laboratory
CCLRC Daresbury Laboratory
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 7.5 M£ from he Office of Science and Technology.
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 sources
R&D towards liquid hydrogen infrastructure and storage system
Tracker (in collaboration with US and Japan)
for phase II:
Focus coils (in absorber module)
Completion of RF sources and liquid hydrogen system and remaining infrastructure
MICE UK has been fully funded for phase I: 9.7M£ OST grant + PPARC
Funding for phase II (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.
US: The Neutrino Factory and Muon Collider Collaboration
founded 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 an improved version of the cooling cell used in « study II ».
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 NFMCC is funded at the level of 3.6 M$/ year by DOE
in addition it received for MICE specifically:
-- an NSF grant of 100k$ a year for the first three years
-- an MRI grant of 750k$ from NSF
this has to cover
-- the personnel for studies and engineering and tests
-- travel and other consummables
-- the hardware construction for
and the recently approved target experiment at CERN ( nTOF11 a.k.a. MERIT)
The collaboration has proposed the following budget for MICE and MUCOOL:
This will 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 3.9M$, for step 6 is 5.3M$
The funding profile pushes step 3 to oct. 2008 and delays MUCOOL
solutions to be found: cash advance from RAL (under investigation)
provision of coupling coil/RF cavities from other collaborators
The Japanese team have been remarkably reliable collaborators in
MUCOOL and MICE. Osaka has also a project PRISM for preparation
of a monochromatic muon beam using an FFAG.
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)
grant request for future neutrino beams is being prepared
(together with HyperKamiokande R&D)
for phase II about 100 OkuYens (~1M$)
to be submitted in november 2005.
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.
Crygenics did not come with it and have 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 consummables
funding 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 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.
Initially a large group ofexperimenters from the HARP collaboration
+ an accelerator group from Frascati
+ an engineering group from Genoa
was hoping to bid for the spectrometer solenoids
(and contributed substantially to the design) but this was discouraged by INFN
R&D and design work for the solenoids, the time of flight and calorimeter was
nevertheless carried out.
Bid was submitted in July 2005 for detectors (Time-of-Flight and calorimeter)
for about 1M€.
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.
will contribute the magnetic sensors to the experiment.
+ 1 PhD student.
The MICE partners: VI. Louvain
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.
We are investigating the effect of having no Cherenkov on the performance of the
downstream particle identification system
The present for of MICE was largely conceived by the CERN group.
Following budget cuts end 2001 the contribution of CERN was reduced to the
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
+RF source + NSF grant 300k$ + MRI grant 750k$.
The NFMCC budget plan for spectrometer solenoids, tracker electronics
and RFCC modules.

(+ 1M$ requested)
-- Switzerland: PSI solenoid + Uni-Geneva-NSwissF (80KCHF/yr)+ 1 PDA+1PhDS
-- Netherlands: Mag probes (in production!) + 1 PhDS
+ Proposal submitted in Italy (TOF, Calorimeter)
