  1. Challenges & Issues for SBNE Nigel S. Lockyer 4/4/14

  2. The Emerging Vision…waiting for P5 • Priorities for the U.S. Particle Physics Program • U.S. High Energy Physics community continues to play a leading role in LHC operations and upgrades • Fermilab hosts world-class accelerator-based neutrino program • Full scope LBNE, underground with >1MW beam power • Active program in short baseline LArTPCexperiments..SBNE • Next gen rare process exp’ts take place this decade…g-2, Mu2e • Explore new particles & forces with a set of exp’ts in the cosmic frontier…..lead DES, partner LSST, CMB, DESI, dark matter exp’s • Participation in the ILC as an international partner • Plans for an upgrade of Fermilab complex to deliver >2 MW • Work with world community on longer term accel technology Requires major investments by non-DOE and international partners

  3. Pre-amble: SBNE and Sterile Neutrinos • Sterile neutrinos are hotter now…after gravitational waves • Fermilab is highly motivated to work with Europe on neutrinos • SBNE has several “off-project” attractive features • Physics is compelling, one million reconstructed events useful for LBNE, advancing the technology reduces risk for LBNE, team building at Fermilab and in Europe • Unfortunately Carlo Rubbia, key ICARUS team members and INFN are unable to make this date…may be available at end of April…exact dates soon…prevents final decisions…but • We should strive to accomplish as much as possible here • We will need to make a few assumptions…some of which I can provide guidance

  4. How to Make Some Progress…external constraints • Constraints from DOE • The building cost must be less than $10M or it will require congressional approval (local language a GPP project) • The detector cost capped at $10M ….due to budget ….funds are coming from redirection from an existing program • A goal is we build and operate the near detector as R&D to avoid the Critical Decision process (CD process) (<$10M and the MIE limit is $2M, otherwise it must go through Congress making a single item above that cost hard to deal with)…I’ll try to better understand this. • The enlargement of the SciBoone Hall should be less than $3M • If these constraints can be met and we agree on details as a team, we can start essentially immediately.

  5. Studies that are needed • It would be helpful to have plots to demonstrate an optimal length along the beam direction for the near detector • This should be a joint Lar1-ND & Icarus study • Identify three coordinators from LAr1-ND, MicroBoone, and Icarus to do work necessary to: • Ensure raw data from all three collaborations is compatible • Provide plots to demonstrate reach of physics • vary a few parameters to show near detector length optimal needed taking into account all three detectors • Estimate running period (POT) neutrinos & if desired antineutrinos • Would a factor of two in neutrinos be useful….Valerie is looking into a new improved horn design…worth it?

  6. Hardware issues…to get a reliable cost estimate • We must have a reliable cost even if not a “CD” project • Provide a better estimate of near detector: • Develop a requirements document for near detector • Include: power, cryogenic distribution, cryogenic design, footprint, and equipment, ??? • Include contingency and risk matrix

  7. Icarus Building Costs • Can we assume that ICARUS is on the surface? • Estimate how long it will run…. has an impact on design of structure and construction materials • Requirements document for that building is needed: • Power, cryogenics, networking, safety systems….. • New Control room in Wilson hall under construction…complete by summer is assumed

  8. Other Areas to Collaborate: US & CERN • We should be looking at a broad program in preparation of signing a joint US CERN agreement for LHC and neutrinos • The cryogenics design should be modern & scalable, in preparation for LBNE (underground) • Membrane cryostat issues can be jointly addressed • A T-200/300 at CERN if it goes ahead should have US involvement …Strait and Nessi • Two phase detectors • Use of CERN test beam should be exploited jointly • Targets & horn can be a joint area of development Presenter | Presentation Title

  9. Conclusion • Much real work to do. • Let’s setup the frame work for progress and begin • Integrate the “three teams” into process being set up • Encourage joining each other efforts • Plan another meeting end of this month • We are trying to allow colleagues to submit NSF grants on time Presenter | Presentation Title
