2. PPA "All Hands" Meeting August 14, 2007 Page 2 An Exciting Time for PPA *David and I take over at a very exciting time for PPA: –The B-factory is running strong. Babar is producing beautiful results. –The LAT has been successfully delivered and integrated onto the GLAST spacecraft. Launch is expected early in 2008. –KIPAC has emerged as a world center for particle astrophysics research. –The SLAC team has become well-integrated into ATLAS at LHC. Preparations are underway for the Tier 2 Center. –SLAC played an essential role in the formulation of the RDR for the ILC, and SLAC staff have leadership roles in the development of the EDR. –We have vigorous R&D efforts in place for future experiments (EXO, LSST, SNAP, SiD). –The Advanced Accelerator R&D effort is going strong (plasma wakefield, laser acceleration, high gradient).

PPA "All Hands" Meeting August 14, 2007 Page 9 International Linear Collider *The highest priority for the international field of particle physics is the full, direct exploration of the TeV energy scale. –with high probability, new physics will be there *SLAC is committed to the ILC –SLAC staff are broadly involved in all elements aspects of the ILC effort –SLAC has played a key role in all aspects of the ILC design (RF power, operational issues, beam delivery, particle sources). –We are lagging behind Europe in detector development due to lack of resources Some hope situation will improve in FY07

13. PPA "All Hands" Meeting August 14, 2007 Page 13 But this is also a time of transition at SLAC… *The B-factory will shut down at the end of FY08. For the first time in its history, SLAC will have no accelerator-based experiment in HEP running on-site. *Stewardship of the laboratory will shift from HEP to BES. *The laboratory leadership is changing: –Jonathan Dorfan will step down and a new Director will take over early in 2008. –Persis Drell has stepped down from her role as PPA Director and will concentrate on the transition from HEP to BES for linac operations. *Stanford will compete for renewal of the contract to manage SLAC. A new strategic vision is being developed for that proposal.

16. PPA "All Hands" Meeting August 14, 2007 Page 16 U.S. High Energy Physics is also in transition… *The focus will shift to CERN and the LHC after the Tevatron shuts down at the end of FY09. There will be no accelerator-based particle physics experiment in the U.S. *The future of ILC is uncertain - Ray Orbach’s speech in February suggested that the proposed timeline may be unrealistic. *Non-accelerator experiments are growing in size, and will comprise a major component of high energy physics research. *Budgets have been tight in 07, and will continue to be in 08.

17. PPA "All Hands" Meeting August 14, 2007 Page 17 The PPA Program Must Adapt *Robustness and flexibility are key. *We need to align to the priorities set by national committees. Science comes first! *We need to capitalize on technical core competencies. *We need to preserve a role for stewardship of a user community. *We need to look for new ways to maintain our “uniqueness”, without a running on-site facility.

18. PPA "All Hands" Meeting August 14, 2007 Page 18 Potential Future Strategy *Three major themes: *The Energy Frontier: –Physics at the LHC (ATLAS, Theory) –Participation in ATLAS upgrade –SiD R&D *Particle Astrophysics and Non-Accelerator Physics –GLAST –LSST leadership. –JDEM participation. –Enhanced role in underground physics, beginning with EXO. –Future ground-based gamma-ray experiments. *Accelerator Science –ILC –LHC upgrade –Enhanced High Gradient research –Advanced concepts

19. PPA "All Hands" Meeting August 14, 2007 Page 19 Changes within PPA *New name: Particle Physics & Astrophysics *New logo: *Some organizational changes: –Tor Raubenheimer will move to Assistant Director for Accelerator R&D. The ILC program will move into Accelerator R&D. –Some components of Accelerator Systems will move to LCLS.

20. PPA "All Hands" Meeting August 14, 2007 Page 20 Summary *There are many challenges ahead, but we are building on a proud history and extremely strong and capable staff. *We believe that we have the makings of an excellent physics program that will keep SLAC at the forefront of the field. There are many discoveries yet to be made. *The evolution of the SLAC scientific program opens up new opportunities for collaboration across traditional disciplinary lines. We look to capitalize on these synergies to strengthen our research programs in all fields.
