Key Fermilab roles in collaboration leadership Executive Committee Members: G.Zeller, J.Strait  Long-baseline physics coordinator:  G.Zeller (co with M.Bishai, BNL) Physics Tools Coordinator: T.Junk  Electron/Photon Simulations – B.Rebel (co with M.Szydakis, UCD) Technical Coordinators:  Beam – A.Marchionni 35 t prototype – M.Stancari (co with M.Convery, SLAC) Software and Computing Coordinator: T.Junk (co with  M.Potehkin, BNL) Jim Strait , Fermilab S&T Review, Nov 5-7 2013 8

LBNE Project Organization  Fermilab plays dominant role in Project Management and Beamline  Fermilab’s role is strong in the far detector - Project Mechanical and Project Electrical Engineers - Responsible for cryogenics and cryostat, and installation & comm. - Fermilab people are present in all aspects of the LAr project  Fermilab leads CF and is fully responsible for all work at Fermilab  Collaboration is integrated into all aspects of the Project Fermilab has ultimate responsibility for the Project . Jim Strait , Fermilab S&T Review, Nov 5-7 2013 9

LBNE Organization will evolve  As international partners become part of LBNE, both the collaboration and project organizations will need to evolve.  An international governance structure will be necessary. First discussions with DOE have occurred concerning formal relations with external partners.  We are looking at structures from other international experiments to learn what we can from them. Jim Strait , Fermilab S&T Review, Nov 5-7 2013 10

LBNE Progress since last S&T Review  CD-1 approval 10 Dec 2012 provides flexibility to refine the scope before CD-2 with partners  CD-1 has enabled us to attract international partners Jim Strait , Fermilab S&T Review, Nov 5-7 2013 11

Engaging the International Community We are in serious discussion with both physics groups  and funding agencies, in: - Brazil - India - Italy - UK New groups from these countries have joined LBNE. We are also in discussions with:  - CERN - LAGUNA/LBNO collab. - Dubna - NESSiE collab. We have had initial conversations with:  - Japan - China - Additional countries in the Americas, Asia and Europe Also exploring how to engage domestic funding sources  beyond the DOE. Collaboration, Project and Fermilab management are  actively working together to develop new partnerships 12 Jim Strait , Fermilab S&T Review, Nov 5-7 2013

Post CD-1 Project Goals Working with international partners (and within the  CD-1 budget) we are developing a plan to deliver an initial project consisting of: - A neutrino beamline - A highly-capable near detector system - A ≥ 10 kt fiducial mass far detector at the 4850 foot level at SURF - A cavern for a full 34 kt detector system. DOE/HEP encourages this approach. The project allows for future upgrades:  - The beamline is designed to handle ≥ 2.3 MW proton beam power - Future detector module(s) can be installed in the underground cavern. 17 Jim Strait , Fermilab S&T Review, Nov 5-7 2013

LBNE Beamline  60 ≤ E beam ≤ 120 GeV  700 kW initially, upgradeable 2.3 MW  Options under study to provide more flux 204 m (reference design) vs. 250 m decay pipe  Air-filled (reference design) vs helium-filled decay pipe  Improved target/horn system design  Jim Strait , Fermilab S&T Review, Nov 5-7 2013 18

LBNE Near Detector System  Muon detectors  Near neutrino detector, Fine Grain Tracker, as developed by partners Jim Strait , Fermilab S&T Review, Nov 5-7 2013 19

LBNE Far Detector Modular detectors in a  common cavern Located at 4850L at  SURF Membrane cryostat  TPC design:   3.7 m drift length  5 mm wire spacing  3 stereo views Detector modules developed by partners will enhance  the reach of the experiment.  These may be of a different design than ours.

Progress – Muon Detector Prototypes Prototypes developed by LANL and universities and  installed in NuMI beamline muon alcove Defined to be Fermilab test-beam experiment T-1046.  May prove to help understand the NuMI beamline, too.  Drexel Stopped Muon Counter R&D Devices Threshold Cherenkov Detector Prototype Jim Strait , Fermilab S&T Review, Nov 5-7 2013 22

Progress – Beamline  Prototype beam position monitors tested in NuMI beamline  Stress and thermal analysis of absorber  Evaluation of types of shielding steel to reduce cost  Target R&D initiated in conjunction with CERN and RAL  Decay Pipe shielding and cooling reviews  Developed design for helium-filled decay pipe Jim Strait , Fermilab S&T Review, Nov 5-7 2013 23

Progress – Conventional Facilities  Geotechnical site investigation performed for beamline at Fermilab  Mapping and laser scanning of existing drifts at SURF - 4850L.  Proposals received for geotechnical site investigation of the underground far detector location at SURF  CF work is the critical path – preliminary design at both sites should start as soon as funding allows. Jim Strait , Fermilab S&T Review, Nov 5-7 2013 24

Progress – Software Development FD Geometries implemented in LArSoft/GEANT4  Several detector geometries => optimization for physics  Preliminary ICARUS geometry  MC samples with several event generators  G4 photon and electron parameterization => e/  separation  Working with LArSoft on reconstruction algorithms,  including LBNE-specific challenges (wrapped APAs) Many physics and detector topics being addressed, e.g.  Energy resolution for EM showers and full event calorimetry  Short-stub efficiency and resolution  Photon detectors  Working closely with Fermilab Scientific Computing Division  on computing resources, framework, etc. See talk by Oliver Gutsche’s talk in the Experiment Support  Facilities Breakout this afternoon Jim Strait , Fermilab S&T Review, Nov 5-7 2013 25

LBNE Cost Range  CD-1 cost range is $805M to $1,100M  We are working to a TPC of $867M, based on the CD-1 scope  In moving detector to 4850L and including near neutrino detector through international partnerships, we will still be managing to DOE cost parameters.  Precise scope that the DOE budget will deliver depends on the developing international partnerships.
