US Contribution to the IDS

This discussion focuses on the framework of the US participation in the IDS for Neutrino Factories and Muon Colliders, rather than specific available resources. It includes a history of previous studies, the role of the Neutrino Factory and Muon Collider Collaboration, and the importance of engineering resources and funding.

  1. US Contribution to the IDS Aka WDS BENE IDS/FP7 at RAL April 28, 2006 A. Bross

  2. I will discuss the framework within which the US participation in the IDS is likely to occur, rather than specifics of resources that might be available

  3. First - A Little History • Study I (1999-2000) • Sponsored by Fermilab ($1M) • First End-to-End Study • Established Feasibility • “Non-aggressive” technology choices • Did not address performance or cost optimization • LARGE cost • Performance goal (useful n/yr) missed by a factor of 3 • Study II (2000-2001) • Sponsored by BNL + NFMCC • Performance optimization • Met useful n/yr goal • 25% Cost Reduction • Study IIa (2003) • APS Neutrino Study • Further cost optimization • 33-40%

  4. International Scoping Study • US participation via Neutrino Factory and Muon Collider Collaboration (NFMCC) (aka MC) • Ad-Hoc participation in the sense that no formal US Lab sponsorship • However, strong participation in all aspects of the ISS and members of the collaboration have taken a leadership role in a number of areas • The NFMCC sees the IDS (WDS) as the next logical step in achieving consensus of ideas for a neutrino factory • Optimized design • Directed Hardware R&D

  5. Neutrino Factory and Muon Collider Collaboration • NFMCC • 30 Institutions, 100+ Scientists and Engineers • Primarily US but has strong Japanese and European Participation • Funded primarily by DOE (Direct funding to the NFMCC – not through a laboratory) • Additional funding from NSF (MRI and Base) and Small Business Innovative Research Program (Also DOE funds) • “The goal of this organization (referred to hereinafter as the Muon Collaboration is to study and develop the theoretical tools, the software simulation tools, and to carry out R&D on the hardware that is unique to the design of neutrino factories and muon colliders. An important part of the program will be an extensive experimental program to verify the theoretical and simulation predictions and to gather the necessary data for a future facility.”

  6. On to the International Design Study • US Participation will very likely be organized through the NFMCC IDS

  7. On to the International Design Study • NFMCC Activities within an International Framework • MICE • MERIT • ISS • Design and Simulation • Detector R&D • What may be difficult to provide will be engineering resources • Extremely important to the success of IDS • Will require discussions with funding agencies, Laboratories and University groups

  8. On to the International Design Study • Funding a large US IDS effort is an open question • However, the EPP2010 Final report (April 26, 2006) states: “Action Item 5: The committee recommends that the properties of neutrinos be determined through a well-coordinated, staged program of experiments developed with international planning and cooperation.” DOE and NSF should invite international partners to initiate a multiparty study to explore the feasibility of joint rather than parallel efforts in accelerator based neutrino experiments. Major investments in this area should be evaluated in light of the outcome of this process. We have a Foot in the Door

  9. EPP2010 Full Text Action Item 5: The committee recommends that the properties of neutrinos be determined through a well-coordinated, staged program of experiments developed with international planning and cooperation. • A phased program of searches for the nature of neutrino mass (using neutrinoless double-beta decay) should be pursued with high priority. • DOE and NSF should invite international partners to initiate a multiparty study to explore the feasibility of joint rather than parallel efforts in accelerator-based neutrino experiments. Major investments in this area should be evaluated in light of the outcome of this process. • Longer-term goals should include experiments to unravel possible charge-parity violation in the physics of neutrinos and renewed searches for proton decay. There may be a valuable synergy between these important objectives, as the neutrino charge-parity violation measurements may require a very large detector that, if placed deep underground, will also be the right instrument for detecting proton decay.
