5. f 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

6. f 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 10 32 cm -2.sec -1 at the 1 st moment of the record store to 0.3 10 32 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.

10. f 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, B s 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.

19. f 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

20. f 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

22. f 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.

32. f 2007 DOE Tevatron Operations Review – Hugh Montgomery 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

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

35. f 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.  1 st 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.
