  1. Rende Steerenberg the PS Neutrino Facility …..Just a few informal slides…. 1st Informal LArTPC at PSNF Get Together 10 August 2011, CERN, Geneve

  2. Contents THE PS NEUTRINO FACILITY….JUST A FEW INFORMAL SLIDES Rende Steerenberg, CERN Switzerland The Proposed Layout The Infrastructure A word on the primary beam Present status The Experimental Requirements

  3. The Proposed Lay-out Near detector THE PS NEUTRINO FACILITY….JUST A FEW INFORMAL SLIDES Far detector Rende Steerenberg, CERN Switzerland Re-use the old TT7 tunnel and cavern to house primary beam line and target station Proton beam to be provide by CERN PS

  4. The Accelerator Complex with PSNF Beam delivery by partial time sharing THE PS NEUTRINO FACILITY….JUST A FEW INFORMAL SLIDES PSNF Rende Steerenberg, CERN Switzerland

  5. THE PS NEUTRINO FACILITY….JUST A FEW INFORMAL SLIDES Rende Steerenberg, CERN Switzerland The Proposed Layout The Infrastructure A word on the primary beam Present status The Experimental Requirements

  6. The TT7 Tunnel Jura THE PS NEUTRINO FACILITY….JUST A FEW INFORMAL SLIDES Geneva Geneva Jura Rende Steerenberg, CERN Switzerland The TT7 tunnel:

  7. Emergency exit TT7 Cavern Front view AD power converters New building needed THE PS NEUTRINO FACILITY….JUST A FEW INFORMAL SLIDES Side view Rende Steerenberg, CERN Switzerland 8 meter under ground Material access shaft

  8. Decay Tunnel THE PS NEUTRINO FACILITY….JUST A FEW INFORMAL SLIDES • No vacuum or helium filled decay tube available to be considered • Consider also muon detectors for beam steering and target/horn alignment Rende Steerenberg, CERN Switzerland • The available decay tunnel is 50 meters long • Cross section: • 3.5 x 2.8 m2 for the 1st 25 m • 5.0 x 2.8 m2 for the remainder

  9. Beam Dump / Hadron Absorber • 4 meter thick beam dump (none sealed iron blocks) • 65 meter of earth • No cooling THE PS NEUTRINO FACILITY….JUST A FEW INFORMAL SLIDES To be reviewed ! Improvement – muon background Rende Steerenberg, CERN Switzerland

  10. The TT7 tunnel towards the target THE PS NEUTRINO FACILITY….JUST A FEW INFORMAL SLIDES Rende Steerenberg, CERN Switzerland

  11. The TT7 Target Cavern TT7 emergency exit TT7 cable & ventilation shaft THE PS NEUTRINO FACILITY….JUST A FEW INFORMAL SLIDES TT7 cavern TT7 cavern TT7 cavern shaft Rende Steerenberg, CERN Switzerland

  12. THE PS NEUTRINO FACILITY….JUST A FEW INFORMAL SLIDES Rende Steerenberg, CERN Switzerland The Proposed Layout The Infrastructure A word on the primary beam Present status The Experimental Requirements

  13. Primary Beam Parameters THE PS NEUTRINO FACILITY….JUST A FEW INFORMAL SLIDES • Exact capabilities of PS and Neutrino facility remain to be determined/confirmed: • PS  beam tests • PSNF  Simulations (FLUKA) • In any case a design should be based on more than maximum capabilities, even if they would be beyond the present PS capabilities Rende Steerenberg, CERN Switzerland

  14. THE PS NEUTRINO FACILITY….JUST A FEW INFORMAL SLIDES Rende Steerenberg, CERN Switzerland The Proposed Layout The Infrastructure A word on the primary beam Present status The Experimental Requirements

  15. Present Status THE PS NEUTRINO FACILITY….JUST A FEW INFORMAL SLIDES Rende Steerenberg, CERN Switzerland • A partial feasibility study, addressing the most critical issues, was made and results have been reported to the CERN management • The collaboration memorandum was discussed in the CERN SPSC in April • CERN has shown a genuine interest, but is awaiting a formal proposal to be evaluated • Presently the potential issue for the near detector location (B181) and the present occupation of the neutrino pit and main floor is being addressed. • The existing rough cost estimate should not be used, but a complete conceptual/technical design study should be made instead (no green light) • Complete and realistic cost estimate • Possible project planning

  16. THE PS NEUTRINO FACILITY….JUST A FEW INFORMAL SLIDES Rende Steerenberg, CERN Switzerland The Proposed Layout The Infrastructure A word on the primary beam Present status The Experimental Requirements

  17. What are the experimental requirements THE PS NEUTRINO FACILITY….JUST A FEW INFORMAL SLIDES Rende Steerenberg, CERN Switzerland • Proton request based on 80’s production yields: • 2.5x1020 for νμ mode  used until now in memorandum, presentations and calculations • 7.5x1020 for νμ mode  to be added ??? • Correct productions yields can only be determined when final design of target and horn are made • What is the realistic time line for the preparation of the experiment ? • Transport and re-commissioning of ICARUS • Design, construction and commissioning of near detector • Other time constraints will/might come from the reconstruction of the PSNF
