Fermilab Steering Group Report

Chapter 1
Executive Summary:
A Plan for Fermilab

The Steering Group's proposed plan

The Steering Group recommends the following plan for the accelerator-based particle physics program at Fermilab.

  • Fermilab's highest priority is discovering the physics of the Terascale by participating in the LHC, being one of the leaders in the global ILC effort, and to make the ILC at Fermilab a reality.
  • Fermilab will continue its neutrino program with NOνA as a flagship experiment through the middle of the next decade.
  • If the ILC remains near the timeline proposed by the Global Design Effort, Fermilab will focus on the above programs.
  • If the ILC departs from the GDE-proposed timeline, in addition Fermilab should pursue neutrino-science and precision-physics opportunities by upgrading the proton accelerator complex.
    • If the ILC start must wait for a couple of years, the laboratory should undertake the SNuMI project1.
    • If the ILC postponement would accommodate an interim major project, the laboratory should undertake Project X for its science capability and ILC alignment2.
  • If the ILC is constructed offshore, in addition Fermilab should pursue neutrino-science and precision-physics opportunities by upgrading current proton facilities while supporting the ILC as the highest priority.
    • The laboratory should undertake SNuMI at a minimum.
    • Alternatively, the laboratory should undertake Project X if resources are available and ILC timing permits.
  • In all scenarios,
    • R&D support for Project X should be started now, with emphasis on
      • expediting R&D and industrialization of ILC cavities and cryomodules,
      • overall design of Project X.
    • R&D for future accelerator options concentrating on a neutrino factory and a muon collider should be increased3.
    • The laboratory should support detector R&D and test-beam efforts for effective use of future facilities.

1 SNuMI is an upgrade of NuMI.

2 Project X consists of an 8 GeV ILC-like linear accelerator and reconfigurations of the existing Recycler and Main Injector. The accelerator portion would be similar in size and scope to the Main Injector. Construction would take four to five years with a few hundred FTEs per year. It would be most effectively mounted as an interlaboratory collaboration.

3 The total annual U.S. R&D budget needed for a neutrino factory and a muon collider is estimated to be approximately $20M.
