Experimental research uses Accelerators complex of accelerators at Fermilab, Tevatron Collider,

Neutrinos Large Hadron Collider, CERN, Switzerland.

Cosmic radiation; optical telescopes charged cosmic rays WIMPS – cold dark matter

Two theoretical physics groups particle physics cosmology.

f Tevatron Collider OperationsTevatron 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.

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,

conferences just a few weeks after the data were taken.

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


f Collaboration Scientific EffortCollaboration 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

f International FinancingInternational 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.

f Safety PerformanceSafety Performance

The Safety Performance in each of PPD and CD has been excellent.

The last recordable injury within CDF, D0, 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.

f Cyber SecurityCyber 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


f Review ScorecardReview Scorecard

2005 Tev Operations Review - 2. Detector Operations No. Recommendations Status/Action 2.2.2 Optimize on a laboratory-

wide basis, the resources needed for Run II with a possible goal of adding resources for detector operations and computing.

Closed. The Fermilab director established the Tevatron Collider Experiment Task Force to evaluate the resources needed for operating the Run II experiments through 2009. The task force included the PPD and CD upper management, the experiment spokespeople, as well as members of the experiments’ operating organizations. Some of the recommendations from that task force were implemented. To a large extent the basic technical needs of the experiments have been satisfied. The Fermilab Directorate introduced a program of International Fellowships to encourage the international participation of physicists in the local operations at Fermilab. The maximum number of RA appointments for the Run II experiments was raised. There is an ongoing need for extra support for guest physicists which is limited by overall laboratory funding. Both experiments have also implemented some changes which increase the efficiency with which manpower is used in operations.

2.2.3 OHEP should follow up on the Programmatic risks: Run II Collaborators, WAN, GRID Infrastructure, and Governmental Directives.

Assigned to DOE

2.2.4 Complete the laboratory-wide bottoms-up planning (2004 Recommendation 3.2.2) so that the prioritization process can be completed.

f SummarySummary

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.
