4. Research Sector 2007 DOE Tevatron Operations Review – Hugh Montgomery

5. Strategy: The Big Picture • Exploit our investments; operate the current program • Develop and Mount a mid-term future program for 2010 - 2015 • Do R&D for the longer term future 2007 DOE Tevatron Operations Review – Hugh Montgomery

6. Tevatron Collider Operations • Run II operations • Are going extremely well • Integrated Luminosity > 2 fb-1 for each experiment • Run IIB: Upgrades are complete, and are invaluable for current high intensity • High Luminosity Operation is successful • The luminosity decays over the course of a store, from 2.9 1032 cm-2.sec-1 at the 1st moment of the record store to 0.3 1032 cm-2.sec-1 at the end of some stores • The trigger suite/mix gets adjusted as the luminosity changes. • The compact nature of the D0 tracker leads to very high occupancies at the highest luminosities – work on reconstruction and identification algorithms is currently in progress. 2007 DOE Tevatron Operations Review – Hugh Montgomery

10. Tevatron Collider Operations • Run IIB Offline computing continues to rely on: • Lab computing infrastructure: buildings, power and cooling and has required very considerable investment • Continued investment in computing resources, networking, and effort • In kind computing from participating international agencies, exploitation of which, in turn, relies on Laboratory and DOE Networking investments • High Luminosity Operation is successful • The offline reconstruction keeps pace with the data taking • Strategies are balances between immediate reconstruction and getting the calibrations in place to minimize multiple passes through reconstruction. • Major re-reconstructions have been successfully mounted using remote resources. Major Grid usage, interoperation of LCG and OSG. • The data are providing physics • Note publications • 2006 Year of the Tevatron, Bs mixing, top mass, W mass, single Top, Higgs limits. • There are results based on 2 fb-1 at the Moriond conferences just a few weeks after the data were taken. 2007 DOE Tevatron Operations Review – Hugh Montgomery

19. Tevatron Collider Resources • Director’s Task Force Report: Fall 2005 • Recommendations aimed at strengthening the support of the experiments • Laboratory has responded: • We try to apply individuals where need is well identified and a match is found • Attempt to gain with efficiencies, common solutions, common groups across the two experiments (eg system management of online, farms operations) • Attempting to maintain strong post-doc cadre by increasing quotas • Have increased the Visitor’s budgets by ~25% • The Collaborations have responded: • Streamlining of effort needs from detector operations through physics analysis 2007 DOE Tevatron Operations Review – Hugh Montgomery

20. Collaboration Scientific Effort • Both Experiments instituted MOUs which are updated every two years. This permits the experiment management to have a gauge of the expectations. Of course any projection of the future are sensitive to numerous influences and can be quite volatile. • Based on 2005,2006, 2007 process is reliable • D0: • 2007, 2008, 2009: Head count 602, 498, 383*; FTE 357, 272, 184 • CDF • 2007, 2008, 2009: Head count ~600*; FTE 392, 297, 236 • * approaches are different • Operations: Detector and Offline needs about 100-120 2007 DOE Tevatron Operations Review – Hugh Montgomery

21. Tevatron Collider Experiment Operations We maintain the support of the Tevatron Collider Experiments 2007 DOE Tevatron Operations Review – Hugh Montgomery

22. International Financing • Laboratory works with the funding agencies through International Finance Committees for each experiment. • Meetings twice (now once) per year • Reports from the experiments • Comments from the funding agencies, for DOE and NSF this is an opportunity to make statements about University support. • There have been significant contributions to detector operations, especially to CDF. • There have been major contributions to computing for both experiments. This enabled D0 to do a complete reprocessing of their Run “IIa” data. 2007 DOE Tevatron Operations Review – Hugh Montgomery

23. Neutrino Operations • Booster Neutrinos • MiniBooNe • SciBooNe ( soon to operate) • Neutrinos at the Main Injector (NuMI) • MINOS • Near Detector underground at Fermilab • Far Detector in Soudan Mine 2007 DOE Tevatron Operations Review – Hugh Montgomery

30.

32. Cyber Security • It is extremely important that our work not be impaired/destroyed by corruption of data or loss of access incidents. • Over the course of the past two years, there have been several reviews and assist visits from DOE at several levels. • The reviews have been consistently good. • We have lost neither data nor analysis time through incidents with our Fermilab major systems. • Continued vigilance is a necessity 2007 DOE Tevatron Operations Review – Hugh Montgomery

34. Publication History 2007 DOE Tevatron Operations Review – Hugh Montgomery

35. Summary • Fermilab Accelerator Based Program continues to be vital • Collider Program is producing the best physics in the world, instantaneous luminosity is growing and the experiments are handling it very well. • 1st results appear based on data only a few weeks old, more generally within year. • Neutrino Operations have been excellent, Booster and NuMI beam power increases and the experiments are operating beautifully. MINOS results were timely, update this summer expected • The experiments do indeed make optimal use of the data provided by the accelerator. • The Collider collaborations understand what is needed to operate the experiments. The effort available will be sufficient to support operations through 2009. • However, that’s not enough. To maximize the exploitation of the physics potential of the program, the Collaborations, the Laboratory, and the agencies need to work together. More would be better. • Our safety and cyber security records over the past two years have been exemplary. • I believe we have closed out all previous Recommendations on Detector Operations attributed to the Laboratory. • We could usefully use increased support for the Collider Program at the level of $1M to ensure the maximal exploitation of the physics potential. 2007 DOE Tevatron Operations Review – Hugh Montgomery
