Alain Blondel 11 October 2010 GDR NEU2012 summary 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 Alain Blondel 11 October 2010 GDR NEU2012 summary

Alain Blondel 11 October 2010 GDR NEU2012 summary 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 summary: Alain Blondel 11 October 2010 GDR NEU2012 summary

Alain Blondel 11 October 2010 GDR NEU2012 summary 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 Alain Blondel 11 October 2010 GDR NEU2012 summary

Single RF Cavity Vacuum Vessel Single cavity vacuum vessel superimposed between the magnet coils 82cm 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

Alain Blondel 11 October 2010 GDR NEU2012 summary 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 Alain Blondel 11 October 2010 GDR NEU2012 summary

Alain Blondel 11 October 2010 GDR NEU2012 summary 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… Alain Blondel 11 October 2010 GDR NEU2012 summary
