Maury Goodman, ANL NOW 2008 September 2008 2 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 2008 3 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 2007. 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 2008 14 Baseball They play almost every day (162-182/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?
15
Maury Goodman, ANL NOW 2008 September 2008 15 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
16
Maury Goodman, ANL NOW 2008 September 2008 16 NO A design plastic filled with scintillator An admirer 32-cell extrusions. The planes alternate horizontal and vertical.
17
Maury Goodman, ANL NOW 2008 September 2008 17 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”

22
Maury Goodman, ANL NOW 2008 September 2008 22 NO A oscillations NO A was approved at Fermilab and construction funds were included in the DOE 07-08 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.

39
Maury Goodman, ANL NOW 2008 September 2008 39 One (unofficial) notion of a LB-DUSEL schedule
40
Maury Goodman, ANL NOW 2008 September 2008 40 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.
