1 The Future of SLAC Jonathan Dorfan, Director SLUO Annual Meeting June 07, 2007

2 SLAC s Future A Treasure-trove of Scientific Opportunity SLAC and its user-community built a world-class scientific laboratory because its program has always been: Driven by outstanding science which has Pushed the limits of discovery Sustained by exceptional technical innovation These characteristics continue to flourish at SLAC and are the foundation of our plans for the future We will continue to be a vibrant resource for our photon science, particle and particle astrophysics communities Allow me to transport you to

3 I see the world s s first x-ray x laser (the LCLS) in its fourth year of operation at SLAC, its users making revolutionary discoveries in the world of the ultra-small and ultra-fast I see the beginning of a first round of major upgrades to the LCLS LS further opening the door to this exciting realm of science I see GLAST in its fifth year of orbiting the Earth, sending down n awe- inspiring images to the Science Operations Center here at SLAC I see us feverishly engaged in exploring the energy frontier as the west-coast coast s s center for ATLAS users while at the same time continuing our central leadership role in both the accelerator and a detector for the International Linear Collider I see 3000 users at SPEAR3 doing world-class science across many disciplines of the ultra-small world The Ultrafast Science Center has become the world s s leading institute for the study of the ultra-fast and ultra-small world. The X-ray X Laboratory for Advanced Materials plays a corresponding role for material science ce

4 I see the world s s most prominent astrophyscists and cosmologists beating a constant path to the Kavli Institute, a Mecca in its field. I imagine the physicists excitedly crowded around the large computer screens in the Kavli building, looking with awe at the images from telescopes like GLAST, AST,.. I see breakthroughs in accelerator techniques that take us to much higher e + e - energies and provide the basis for 5 th generation light sources I see the BABARB AR Collaboration still publishing important papers and graduating fabulous young students I see the Large Synoptic Survey Telescope (LSST) coming on line e in Cerro Pachon,, Chile sporting the world s s largest digital camera built here at SLAC I see a theoretical effort in particle and astroparticle physics and cosmology that is defining the new world I I see EXO deep underground solving the mystery of the true identity ity of the neutrino The Vision Is Real: Our Users Are Crucial to Making It Happen!

5 SLAC Future Responding to the Changing Scientific Landscape The balance of the scientific elements of the Lab are changing: The size of the photon science program will grow dramatically in the next few years By 2009, the on-site accelerators, SPEAR3 and LCLS, will both be doing Photon Science. By 2009, DOE s Basic Energy Science office will be the dominant budget at SLAC Particle and Astroparticle physics will be focused on ATLAS, BABARAR analysis, GLAST, the ILC, LSST, EXO, theory We will continue our role as the leading Laboratory worldwide in Accelerator Science We have been through dramatic program shifts before we will make this transition successful just as we did in the past 5

16 Particle and Particle Astrophysics Program PEP-II will have its final run in 2008 ending a 40-year era of providing on-site, frontier HEP accelerator facilities While this represents a major change, SLAC will remain a vital and vibrant laboratory for r its high energy and particle astrophysics users SLAC has technical, human, physical and computing infrastructure that provide unique opportunities for frontier science ventures that are beyond the scope of the University environment The parameters of the SLAC electron and positron beams are unique and will remain crucial to the development of new accelerator techniques With the successful completion of GLAST, SLAC has demonstrated that it can lead a major, space-based telescope construction project with full participation of its international users. Kavli Institute provides an exceptional conduit for our user community to engage broadly in particle astrophysics 16

17 Particle and Particle Astrophysics Program No laboratory has contributed more broadly to the development of the linear collider than SLAC. The laboratory remains central to the ILC s future success The SLAC-based user group has rapidly developed a major presence in ATLAS, exemplifying the strength of SLAC to facilitate such opportunities SLAC remains a powerful center of theoretical particle and astroparticle physics. The theory expertise greatly augments the user-based experimental activities With Babar, SLAC has demonstrated its ability to manage all aspects of massive data streams/analysis in the international arena. This capability remains crucial to the next 5+ years of Babar analysis and underpins the TIER-II ATLAS effort. It provides a platform for new ventures like LSST,. SLAC has an important role for facilitation of the user community in major PPA ventures and it retains the core competencies and capabilities to do that very successfully 17
