  1. Status of Neutrino experimentalPhysics and AIDA Septembre 2013 Sterile neutrinos Long baseline neutrino experiments

  2. 1. Sterile neutrinos Onlythesetwomay use solidscintillator

  3. Awarded CD0 atFermilab (willbestudiedtowards TDR) “We note that within the Advanced EuropeanInfrastructures for Detectors at Accelerators (AIDA) project [206], whose time line runs from 2011 to 2015, detectors similar to those planned for nuSTORM will be built and characterized at CERN. The motivation is to test the capabilities for charge identication of 5GeV/c electrons in a Totally Active Scintillator Detector and 5 GeV/c muons in a Magnetized Iron Neutrino Detector (MIND). These detector prototypes will provide further experience in the use of STL technology, and SiPMsand associated electronics, to complement the already large body of knowledge gained through past and current operation of this type of detector.” Awarded CD0 atFermilab --

  5. PRACTICALITIES

  6. Implementation, at CERN: • Principal issue: • SPS spill is 10 μs: • Implies bend for proton or pion beam • Or development of fast extraction • Two options: • NA implementation: • Possible exploitation of synergies with ICARUS/NESSiE • NA-to-WA implementation: • Advantage is proton/pion bend not required; • Longer baseline must be tuned to larger muon energy (possibly an advantage too)

  7. Implementation, at CERN: • Principal issue: • SPS spill is 10 μs: • Implies bend for proton or pion beam • Or development of fast extraction • Two options: • NA implementation: • Possible exploitation of synergies with ICARUS/NESSiE • NA-to-WA implementation: • Advantage is proton/pion bend not required; • Longer baseline must be tuned to larger muon energy (possibly an advantage too) North area extension

  8. Event rates per 10~ton at the near detector station arXiv:1308.6822v1

  9. How canLBNX profit fromnuSTORM?

  10. CP asymmetry decreases as sin2213 increases… Systematics! First maximum • Challenge of precision! • Flux and cross-sections must be known to <<5% • hadro production experiments (NA61@CERN) + near detectors  cross-sections to 5% • needed to measure cross-sections • to 1% precision  mini neutrino factory (first step muon storage ring) • Old idea, re-publicized in 2009. Now proposed under name nuSTORM Bross@NUFACT11 TASD, LArg…

  11. Zooming on «parametric» systematic errors As expected13dominates

  12. Zooming on detection-related systematics As expectede dominates! CP Emphasizes once more the importance to know cross-section x efficiency for the e (in far detector) /  (in near detector)

  13. It seemsthataddingprecise signal cross-section ( =. ) -- for near detector normalizationchannel ( or ) -- and far detector signal channel (eore) canimprove the final reach of a long baselineexperimentconsiderably. nuSTORMexposure of near detector and far detector prototype -- size 1-100 tons shouldprovide the proper data set for 1% meaasurement of cross-sections. It fitswell in a stagedapproachwith excellent physics output ateach stage A few yearsbefore the LBL experimentstarts.

  14. Size required for containment of had. showers CERN seems committed to provide support for these important developments Also test of MIND/TASD prototype in beam (AIDA)

  18. Conclusions I canseethree applications of the AIDA detector R&D -1- as TASD and MIND for near detector @ LBNX (in LBNO EOI) -2- near and far detector for nuSTORM (proposedunderstudy) -3- MIND detector for (300ton) prototype LArg + MIND operation (couldbe cross-section detector @ nuSTORM?) -4- MIND detector for (20-30kton) Larg + MIND combinationat LBNX
