V. Palladino Summary of MMW Workshop
… from BENE proposal :
coordinate and integrate the activities of
the accelerator and particle physics communities working together,
in a worldwide context,
towards achieving superior
neutrino (ν) beam facilities for Europe.
1) to establish a road map for upgrade of our present facility and
the design and construction of new ones
2) to assemble a community capable of sustaining
the technical realisation and scientific exploitation
220 signatures
of these facilities
3) to foster a sequence of carefully prioritized&coordinated
initiatives
capable to establish, propose and execute

Fermilab and Brookhaven
•
Fermilab and Brookhaven concepts have several elements in common:
– Increase the repetition rate of the existing machine (MI or AGS)
– Decrease the fill time of the existing machine by using a (sc) linac
– Increase the injected beam intensity by using a linac (or synchrotron)
– Rely on previously developed SCRF technologies
•
Both conceive of upgrade paths that could go another factor of 2-4
•
The BNL concept features a 1.2 GeV superconducting linac as the injector
into the (upgraded) AGS
•
Fermilab has two implementations under evaluation, each with capability to
inject into the Main Injector and to provide stand-alone 8 GeV beams:
– 8 GeV synchrotron (with 600 MeV linac injector)
– 8 GeV superconducting linac

2.
Make as many charged pions as possible
 INTENSE PROTON SOURCE
(In practice this seems to mean one with a
beam power of one or a few MW)
Capture as many charged pions as
possible
 Low energy pions
 Good pion capture scheme
3. Capture as many daughter muons as
possible within an accelerator
 Reduce phase-space occupied by the
ms
 Muon cooling – needs to be fast

V. Palladino Summary of MMW Workshop
Superbeam and Neutrino Factory R&D
Proton driver (and accumulator etc..)
Target area, targetry & collection
Muon Ionization Cooling.
Acceleration.
Detectors
Superbeam/Neutrino factory FP6 design study proposal
in preparation for early 2005
--> be ready for decisions in 2010!
NB Nearly all of the accelerator R&D has, from the start, had a
healthy level of global collaboration. Examples: MUSCAT,
MUCOOL, Targetry, HARP, Design Studies I and II, …
58
Targetry & Collection:
Proposal to test a 10m/s Hg Jet in a 15T
Solenoid with an Intense Proton Beam
59
Note: The solenoid is under construction, and the Hg-jet under development.
Participating Institutions
1) RAL
2) CERN
3) KEK
4) BNL
5) ORNL
6) Princeton University
MICE – a Global Muon Ionization Cooling
Experiment
Build & operate a section of a realistic cooling channel & measure
its performance in a muon beam (at RAL) for various operation
modes & beam conditions.
Has Scientific Approval and is seeking funding.
NB US, Europe and Japan !!!!!!!!!

Acceleration
61
Muon Collaboration
Much progress in Japan with the
development and demonstration
of large acceptance FFAG
accelerators.
Latest ideas in US have lead to
the invention of a new type of
FFAG (so-called non-scaling
FFAG) which is interesting for
more than just Neutrino Factories,
& may require a demonstration
experiment (plans are developing)
Perhaps US & Japanese concepts
are merging to produce something
better ??
New US Acceleration Scheme … still evolving

Neutrino Factory: towards cost reduction

V. Palladino Summary of MMW Workshop
Conclusions:
An European strategy, based on a new powerful
MWatt proton Driver
in WW context !
for a new European
Neutrino Complex
comprising part or all of
Superbeam
Eurisol/Betabeam
Neutrino Factory
deserves careful attention

V. Palladino Summary of MMW Workshop
(at least) one point that does need clarification ….
The richness of options
 Superbeam
 Betabeam
 Factory
and the animated debate on the choice of <E > & Ldetector
should not obscure the fact that ALL options DO need
a Megawatt Proton Beam
& a Megawatt Target-Collection Complex
This emerges consensually as
the highest priority
for European accelerator 
