f Tevatron Collider Operations § Run II operations Ø Are going extremely well Ø Integrated Luminosity > 2 fb-1 for each experiment Ø Run IIB: Upgrades are complete, and are invaluable for current high intensity § High Luminosity Operation is successful Ø The luminosity decays over the course of a store, from 2. 9 1032 cm-2. sec-1 at the 1 st moment of the record store to 0. 3 1032 cm-2. sec-1 at the end of some stores Ø The trigger suite/mix gets adjusted as the luminosity changes. Ø The compact nature of the D 0 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 6

f Tevatron Collider Operations § Run IIB Offline computing continues to rely on: Ø Lab computing infrastructure: buildings, power and cooling and has required very considerable investment Ø Continued investment in computing resources, networking, and effort Ø 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 data are providing physics Ø The offline reconstruction keeps pace with the data taking Ø Strategies are balances between immediate reconstruction and getting the calibrations in place to minimize multiple passes through reconstruction. Ø Major re-reconstructions have been successfully mounted using remote resources. Major Grid usage, interoperation of LCG and OSG. Ø Note publications Ø 2006 Year of the Tevatron, Bs mixing, top mass, W mass, single Top, Higgs limits.

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

f 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 § D 0: Ø 2007, 2008, 2009: Head count 602, 498, 383*; FTE 357, 272, 184 § CDF Ø 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 20

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

f 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 D 0 to do a complete reprocessing of their Run “IIa” data. 2007 DOE Tevatron Operations Review – Hugh Montgomery 22

f Safety Performance § The Safety Performance in each of PPD and CD has been excellent. § The last recordable injury within CDF, D 0, or MINOS occurred nearly two years ago. § Since then there have been a few first aid cases. § There have been no recordable injuries involving Users at these facilities either only one or two first aid cases. § In CD the division recently passed the milestone of five years without a DART case. 2007 DOE Tevatron Operations Review – Hugh Montgomery 30

f 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 32

f Summary § Fermilab Accelerator Based Program continues to be vital § 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 $1 M to ensure the maximal exploitation of the physics potential. Ø Collider Program is producing the best physics in the world, instantaneous luminosity is growing and the experiments are handling it very well. Ø 1 st results appear based on data only a few weeks old, more generally within year. Ø Neutrino Operations have been excellent, Booster and Nu. MI beam power increases and the experiments are operating beautifully. MINOS results were timely, update this summer expected Ø The experiments do indeed make optimal use of the data provided by the accelerator. 2007 DOE Tevatron Operations Review – Hugh Montgomery 35
