Another Roadmap Example ILC – Fermilab’s Highest Priority Project X Construction ILC R&D ILC Decision, Engineering, Industrialization, Construction + Running Running SCRF Linac R&D, Engineering, Industrialization, Large system test Project X R&D, Engineering In all scenarios: LHC Upgrade, Higher Energy Colliders R&D, Particle Astrophysics (Dark Matter, Dark Energy) sNuMI Construction ILC R&D ILC Decision, Engineering, Industrialization, Construction + Running sNuMI Running Note that sNuMI and Project X plans are detached from the ILC timeline.

sNuMI vs. Project X Physics Opportunities –Neutrino, Flavor –sNuMI – great for near term goals –Project X – greater physics opportunities, stage to next facilities Constructions –M&S: sNuMI is much cheaper –Human Resources: Project X requires much more but should be done by a large collaboration with National and International collaborations Operations –Expect running Project X to be easier and cheaper than sNuMI (30+ year old facilities) and to require less people Project X – advancing ILC –Technology toward cheaper ways, Fermilab’s preparation for ILC –Concerns: international perception about FNAL and US’s commitment on ILC Project X – step toward possible future facilities –Beam to DUSEL, energy frontier beyond ILC/LHC
