Maury Goodman, ANL NOW 2008 September Preface: “Long-Baseline” Definition Dictionary definition of long - “having considerable linear extent in space” Longer than before / Off the site of the accelerator Beam -- L >> length of beam pipeYES Which implies the far detector sees a point source of neutrinos Physics – L >> E/(2.54 m 32 2 ) ~ 1500km NO
Maury Goodman, ANL NOW 2008 September Preface: [Factors in North America/US] National Planning in the US is done by a panel called HEPAP (High Energy Physics Advisory Panel) Long-Term Planning is done every few years by subpanels A recent innovation is to have a panel called P5 (Particle Physics Project Prioritization Panel) maintain a roadmap. The highest priority project in a 2001 report was the ILC (Bagger-Barish Panel) The ILC Central Design Group Reference Design Report reported an ILC cost in August The advertised cost was $6.6B. The estimated US project cost is $21.9B. [These are the same number!] Too much ->-> Therefore new study

Maury Goodman, ANL NOW 2008 September Plus more baselines… To have some more facts in this talk, I’ll mention several things having to do with baseball*. Fully realizing a large fraction of my audience doesn’t care in the least about baseball

Maury Goodman, ANL NOW 2008 September Baseball They play almost every day ( /year) Many fans appreciate statistics You can understand about 70% of the game in 30 minutes Much that remains is fairly subtle Huge influence - metaphors on English language (MVP, double play, off base, hit it out of the park, pinch hitter, foul ball, all-star, big league, rain check, …) Most common questions when I take a European to a baseball game (~40,000) –Why are there no policeman? –What is light beer?
Maury Goodman, ANL NOW 2008 September NO A-Where? The Ash River site is the furthest available site from Fermilab along the NuMI beamline. This maximizes NO A’s sensitivity to the mass ordering. Off-axis

Maury Goodman, ANL NOW 2008 September NO A A significant Issue It takes a long time to build & fill It is desirable to take data before it is complete Gluing & Structural Engineering challenges “The problem with plastic is that it is plastic”

Maury Goodman, ANL NOW 2008 September NO A oscillations NO A was approved at Fermilab and construction funds were included in the DOE proposed budget ($12M first year of $260M) Funds also in Congressional budgets, but retroactively zero’d in a December 07 compromise P5 report recommended NO A, but not in all funding scenarios. A supplemental funding bill in July 08 included $9.2 M for NO A It recently passed its (second) CD2 review – not yet signed. Hardware & Civil projects that had been delayed are gearing back up.

Maury Goodman, ANL NOW 2008 September One (unofficial) notion of a LB-DUSEL schedule
Maury Goodman, ANL NOW 2008 September DUSEL long-baseline is a vision The vision requires: (all cost figures MCG rumor quality) –DUSEL ($500M+) –A new beamline at Fermilab ($250M) –Project X ($1B) –A new huge detector ($500M-1B) None of these currently exist or are “approved” It is not clear that this fits the funding assumptions of P5, or that it is a community consensus.
