.. Future neutrino facilities offer great promise for fundamental
discoveries (such as CP violation) in neutrino physics, and a post-LHC
construction window may exist for a facility to be sited at CERN.
..CERN should arrange a budget and personnel to enhance its
participation in further developing the physics case and the technologies
necessary for the realization of such facilities. 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 future projects,
and is therefore required.
..A direct superbeam from a 2.2 GeV SPL does not appear to be the
most attractive option for a future CERN neutrino experiment as it does
not produce a significant advance on T2K.
..We welcome the effort, partly funded by the EU, concerned with the
conceptual design of a β-beam. At the same time CERN should support
the European neutrino factory initiative in its conceptual design.

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:
additional intermediate 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)

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

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.

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

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

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!
