m e Conversion at Fermilab ? Steve Geer BNL-MECO Meeting January 2006
Steve Geer BNL-MECO Meeting January 2006 page 2 Fermilab Interest - 1 A small group of scientists at Fermilab have begun discussing possible options for a m e conversion experiment at FNAL: Accelerator Division Particle Physics DivisionChuck AnkenbrandtFritz DeJongh Dave Neuffer David Finley Milorad Popovic Steve Geer Eric Prebys Ron Ray If there is a practical & fiscally attractive solution at FNAL for a cutting edge m e experiment, then there are FNAL people interested in the experiment.
Steve Geer BNL-MECO Meeting January 2006 page 3 Open Questions • Is there a way to provide an adequate beam intensity with an acceptable bunch structure for a m e experiment at FNAL without significantly impacting the neutrino program ? • How would the experiment evolve from the Booster era to the FPD era ? • Cost and Performance ? • Should the beam/experiment be MECO-like, PRISM/PRIME -like, or something else ?
Oddone P5 Talk (9/2005) ILC Proton Driver RF module assembly and testing Industrialization Looks good! Press for early decision LHC discovery: GO CDR effort 2005 2006 2007 2008 2009 Not affordable This induces other program choices Nothing yet Much longer R&D needed Steve Geer BNL-MECO Meeting January 2006 page 4 FNAL Vision The future Fermilab program faces a major branch point when it is known whether the ILC is on a fast track or delayed. This “decision point” is expected to occur next year. If we are on an ILC fast track, it may not be realistic to expect a major new experimental initiative at Fermilab beyond NOvA … at least not for a long time, unless there is a significant non-US contribution.
Steve Geer BNL-MECO Meeting January 2006 page 5 Relationship with Fermilab Proton Driver If we are on an ILC delayed track, we expect a push for the Fermilab Proton Driver (FPD). In the recent FPD physics study, a low energy muon program was identified as a promising candidate to complement the neutrino program at FNAL in the FPD-era. LOCAL THOUGHTS:If there is an attractive solution for a m e conversion experiment at FNAL, I can imagine it being proposed after the FPD decision point (sometime in 2007). The proposed experiment might start at the existing Booster, & then become part of the FPD program (Think of the NOvA plan).
