NEU2012 towards a concrete proposal by the
neutrino community.
(or: Laguna, EUROnu and others together)
-- Test beam
-- Road map
-- “little neutrino beam”
-- “bigger neutrino beam”
-- Technical accelerator R&D

comments
there seems to be little interest in the CNGS beam as is. Main limitations being
absence of near detector, high energy and intensity limits.
Beam needs to be rebuilt for e.g. electron neutrino search.
2. May as well build a new one pointing at either
-- location >>1000km (where CP violation and matter effects can be separated)
 fine grain detector: segmented scintillator or liquid argon
may as well foresee neutrino factory-type baseline (> 2000km)
energy ~ 4 GeV  PS2 superbeam and/or neutrino factory
-- or << 300 km where matter effects are small and water Cherenkov is very good
also consistent with beta beam
energy < 600 MeV  SPL superbeam or/and beta beam

A very sketchy and “obvious” proposal
Magnetized Iron Muon Spectrometer 1m 8m
Fully active segmented scintillator 4m
12m
Could be vertical
WHAT IS THE FID. VOLUME?

TEST BEAM
Seems an obvious case:
around H8 magnet test WC, LArg and TASD prototypes
with the MIND prototype as muon catcher/spectrometer
-- TASD (and LArg?) in magnetic field?
Already some money from AIDA for some basics
action: draft proposal by end of november 2010 submission end of year
closure of CERN beams in 2012 forces us to recast program
2010 write proposal to CERN for use of test beam before Xmas
2011-Q1 kick off meeting
2011-Q3 first test with baby-INO but need muons of 1-2 GeV…
2012 construction and cosmic tests of TASD and MIND detectors
2013 fuller tests in NH

Single cavity vacuum vessel superimposed between the magnet coils

79cm
Single RF cavity vacuum vessel will potentially be used in a 3 T large bore magnet to perform RF breakdown test measurements in a magnetic field at CERN in support of the MTA at FNAL or in support of MICE

problem is that this gives very low enery electron neturinos
can we store muons?
a 600 MeV/c muon storage ring gives neutrinos with the
same spectrum as gamma = 100 beta beam –much cheaper
to be discussed but a very nice and original proposal.
similar ideas exist at Fermilab with anti-proton storage ring

Technical accelerator R&D
There are very good synergies between CLIC and Neutrino Factory
In particular field emission by RF cavities in intense electric and magnetic field
(MOU with Fermilab on collaboration on this subject)
Could the NA test be a beginning of this?
Other possibilities involve simulation tool and diagnostic tools workshop etc…
