CERN neutrino future plans AIDA neutrino meeting

1. CERN neutrino future plansAIDA neutrino meeting M.Ne. 24-September-2013

2. CERN EU strategy mandate ………. CERN should develop a neutrino program to pave the way for a substantial European role in future long-baseline experiments. Europe should explore the possibility of major participation in leading long-baseline neutrino projects in the US and Japan.” “Future major facilities in Europe and elsewhere require collaboration on a global scale. CERN should be the framework within which to organize a global particle physics accelerator project in Europe, and should also be the lading European partner in global particle physics accelerator projects elsewhere. Possible additional contributions to such projects from CERN’s Member and Associate Member States in Europe should be coordinated by CERN.”

4. CERN neutrino project : 3 main activities in the near future (3-4 years) • Foster and support Detector R&D for neutrinos in Europe, providing an effective technological platform • Terminate the studies for the implementation of a classical neutrino beam at CERN in the nord area (CENF) • Prepare a strategy for a long baseline facility with the Japanese and US colleagues, with an important European involvement

5. The CENF Facility under study Primary beam ~600m from target area Near Detector Facility Far Detector Facility @456m from target, EHN1 extension @1600m from target Secondary beam In front of EHN1 Venice – 13 March 2013

6. First goal: EHN1 extension Will host several detectors to be tested in charged beams and neutrino beams

7. First goal: EHN1 extension

8. First goal: EHN1 extension This first facility could be ready by mid 2015 !

9. Secondary beam under study

10. Secondary beam under study ~110 m decay region 100 GeV primary beam This facility could be ready by mid 2017 !

11. Secondary Beam: Focusing /cm2 a.u. A.Ferrari et al. • Focus pions at ~ 5 GeV • Max power 240 KW • Target inserted in horn followed by reflector Perfect focus within 1 rad Reference configuration Field (Tesla) New “best” configuration R (cm) REFLECTOR 4 m length 150 kA HORN 4 m length 240 kA • Far detector νμ spectrum • Green: hypothetical perfect focusing • Purple: present design TARGET 1 m graphite , r=8 mm Fully inside horn • Far detector ~1M νμ /yr , ~20K νe/yr

12. Detector R&D • WA104 : ICARUS 150t and 600t • 150t as a new object (LAr TPC) which could become a SBL near detector or a basic module of a very large long baseline detector. Could be the focal point of a European-US basic R&D on LAr TPC of a new generation. To be tested in charged beams and fully debugged in a neutrino beam. An effective R&D tool for all future activities • 600t, todat at GS and to be moved to CERN and refurbished following the 150t new experience. Can serve as SBL far detector at cERN or as long baseline near detector at FNAL. Today it is still the most complete and functioning LAr TPC available!

13. Detector R&D ICARUS 150T ICARUS 600T

14. Detector R&D • WA104 : NESSiE spectrometer • Aircore new type of spectrometer (R&D necessary) • Iron core spectrometer (Opera Components)

15. Detector R&D • WA105 : LAGUNA 2 phases LAr TPC • a first prototype 1 x 1 x 3 m as a first demonstrator at large scale • a large prototype 6 x 6 x 6 m3 as final technology demonstrator in view of a very large long baseline far detector. To be first qualified on charged beams in the nord area.

16. Detector R&D

17. In practice CERN could help • In providing a test beam facility for future neutrino detectors (charged and neutrino beams if requested) • Providing technical help in the engineering and procurement of cryostats and cryogenics plants • Providing technical help for issues related to controls and DAQ • Offering a technological and administrative platform for detector and beam components R&Ds (details to be defined) • Providing an European basis for Long baseline R&D and later construction activities steered by the physics community

18. Long baseline • ICARUS is now member of LBNE in the US • LBNO is starting first negotiations with LBNE • LBNE is not yet approved, but passed the first review in the US with a potential of 867M$ • DOE is asking CERN for help in the US neutrino program (R&D and construction) • LBNO is still continuing to consider a full European solution, with beam from CERN and Protvino

19. An intensity facility in the US ν ν ν ν ν ν ν For : - neutrino beam experiments (CPV, MY,..) - proton decay - supernova neutrino physics - atm. neutrino physics

20. Design and R&D A possible CERN Picture CENF Design Design and R&D 2014 2018 EHN1 constr. LAr1-ND @FNAL 2015 Detectors and Beam construction & installation EHN1 ready New 200T Lar TPC construction LAGUNA proto construction 2016 LBN design and R&Ds at CERN (det + beam+infra) 2023-25 (IF) CENF beam construction 35 Kt Det. Underground in the US LBN 0.7 MW 2017 Charged beam tests 70 Kt Det. CENF ready (IF) LBN 2.3 MW 2018 Neu beam tests

21. Summary : “pave the way ….” • A neutrino project is now starting at CERN on the benefit of the entire community • Next 3-4 dedicated to R&D and test of prototypes of detectors and beam elements • Still possible to reconsider the opportunity of a neutrino beam at CERN as an effective test bench for future activities and an opportunity for a SBL type of physics (steriles, cross-sections, …) • Next 3-4 years also dedicated to the design and decision towards a long baseline
