a step of our long term strategy … ECFA … BENE/HIPPI … DS
influence CERN R&D choices (mid 2006)
propose a new Neutrino Complex for its agenda
make it a credible option by end 2008 More immediately campaign for a new high intensity Proton Complex
…. SPL and beyond … persuade CERN to restore a little kernel activity
ablo to cluster EU labs around it re-propose Workshop in 05
ie produce new fresh work for an updated COMPREHENSIVE “BOOK” end 05

Study of the Physics of Neutrinos
Sponsored by the American Physical Society Divisions of — Particles and Fields Nuclear Physics Astrophysics Physics of Beams
Organizational meeting was held December 2003.www.neutrinooscillation.org/studyaps/
Final report will be completed August 2004.

The Purposes of the Study
— Primary Purpose —To move towards a coherent strategy for answering the
open neutrino questions — a clear, unified plan that funding sources can easily consider and promote.
To this end, we will—• Identify the most important questions• Evaluate the physics reach of the proposed ways of
answering them• Examine how different facilities and experiments
complement each other• Create a decision tree• Determine an intelligent sequence of facilities and
experiments

TargetsOrganizing Committee and Working Group Leaders
hold Mid-Course Correction Meeting April 1-2 or 4-5.
Purpose: To assess the progress of the Working Groups and to coordinate their activities.
Entire Study holds three-day Final General Meeting during June 23-28 in Aspen.
By the end of this meeting:• The working group findings• Final cross-working-group coordination• Preliminary study conclusions

We should be able to make a very strong case for a robust, exciting neutrino program.
Both DOE and NSF have made it clear that they will be listening to us.
Good Luck!

• Need for higher beam performance (brightness*, intensity) to:
– Reduce the LHC filling time,– Improve the reliability in the generation of the ultimate
beam actually foreseen for LHC,
– Increase the proton flux onto the CNGS target,
– Increase the proton flux to ISOLDE,
– Prepare for further upgrades of the LHC performance beyond the present ultimate.
* For protons, brightness can only degrade along a cascade of accelerators Any improvement has to begin at the low energy (linac) end
