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 10

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
• ccurred 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 11

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

• 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

INFN Visit to Fermilab 17 Sep 2013

• 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.

LBNE Beamline

• 60 ≤ Ebeam ≤ 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 19

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 20

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.

Jim Strait , Fermilab S&T Review, Nov 5-7 2013 21

Progress - 35t Prototype Detector

• At Fermilab’s PC-4, built

by Fermilab staff + vendor (IHI)

• Initial run for purity testing

to start later this month

• Phase II run with TPC is

planned to start next fiscal year.

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.

Jim Strait , Fermilab S&T Review, Nov 5-7 2013 23

Progress – 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
• Prototype beam position monitors

tested in NuMI beamline

Jim Strait , Fermilab S&T Review, Nov 5-7 2013 24

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 25

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
• n computing resources, framework, etc.
• See talk by Oliver Gutsche’s talk in the Experiment Support

Facilities Breakout this afternoon

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.

Jim Strait , Fermilab S&T Review, Nov 5-7 2013 28

LBNE Key Near Term Plans

• Continue to develop partnerships and involve

collaborators in their areas of interest; work towards real commitments and corresponding collaboration and project governance mechanisms

4850L to understand range of cavern span possibilities and start excavation design

• Complete 35t prototype cryostat purity run and

install 35t phase II TPC

geometry and helium fill / cooling

Conclusions

• LBNE will provide dramatic improvement in CP violation,

mass hierarchy, non-standard interactions relative to current generation experiments

• Longer baseline and very large instrumented targets for

a comprehensive program

• Large detectors probe physics not accessible in other ways
• Proton decay (Grand Unified Theories)
• Supernova burst neutrinos from intra-galactic distances
• LBNE has received approval to begin this program
• It will be a major US HEP facility for the 2020’s
• With a budget of $867M we are proceeding with the

most important aspects in the first phase and actively working with partners to expand the scope

• LBNE will develop into a world center for neutrino physics

to complement hadron/lepton colliders elsewhere
