  1. Vision for SLAC Science Persis S. Drell Director SLAC SLUO 2008 Annual Meeting

  2. SLAC Mission • Investigate the structure of matter and how it behaves on multiple timescales, length scales, and energy scales addressing fundamental questions including: • Understanding the basic science of matter • Investigations of materials related to energy and the environment • Probing the organizing principles of bio-materials and processes • Elucidating the fundamental forces and constituents of the universe • We execute the mission through the operation of our user facilities and the scientific programs we support. SLUO 2008 Annual Meeting

  3. National Laboratory Role • Provide technical and scientific leadership • Design, build and operate facilities • Provide unique technical capabilities in management and construction of large scale projects • Paradigm of user support is shifting • Photon science user community is changing • Particle physics user community is changing SLUO 2008 Annual Meeting

  4. Tale of Two Transitions at SLAC • Major transition of scientific portfolio • Going forward major onsite user facilities operating for photon science rather than particle physics • Transition to multi-program environment • We have optimized locally for many years • Transition now to optimizing for the institution as a whole SLUO 2008 Annual Meeting

  5. Scientific Vision for SLAC • Strong Photon Science program • World leading on site facilities • Strong Particle Physics and Astrophysics • Focus on energy frontier and cosmological frontier • Accelerator science • Core competency of the laboratory • Key tools for discovery in many scientific areas SLUO 2008 Annual Meeting

  6. LCLS: Linac Coherent Light Source SLAC ACCELERATOR FACILITIES Turn-on in 2009: LCLS will be the World’s First X-ray Laser SLAC ACCELERATOR FACILITIES FACET LCLS SPEAR 3 SLUO 2008 Annual Meeting

  7. SLAC Photon Science Future: LCLS • X-ray Free Electron Laser (LCLS) • Use the last 1/3 of the SLAC Linac to produce a new kind of light source • LCLS is currently under construction; will be complete in 2009/10 • X-ray Lasers will open the Ultra-Small and Ultra-Fast Worlds –Realm of LCLS— First Light 2009 • 1012 photons/pulse • 800 eV – 9 KeV • 200 fs pulse at commissioning • few * 10 fs within 1-2 years • fully coherent at x-ray wavelengths SLUO 2008 Annual Meeting

  8. SLAC Photon Science Future: SSRL and Beyond • SSRL • X-Rays have opened the Ultra-Small World -- Realm of SPEAR3 – Operating Now • 1012 photons/sec from high brightness undulator • 400 eV –40 KeV • 50 ps pulse • limited coherence at x-ray wavelengths • Future: PEP-X SLUO 2008 Annual Meeting

  9. Particle Physics Today • The most exciting time scientifically in my career lifetime • Opening of TeV frontier • Mystery of neutrino masses and mixing • Dark Energy • Dark Matter • Healthy particle physics program very important to US going forward • Priority for SLAC SLUO 2008 Annual Meeting

  10. New Paradigm for the US • The frontier of accelerator based particle physics is off shore for the next decade • Particle physics will thrive in the next decade • Will the US continue to play a leadership role? • How can national laboratories help support the user community to be effective participants • At accelerators abroad? • In non accelerator based experiments? SLUO 2008 Annual Meeting

  11. SLAC Support for Users Going Forward • Highest priority for the field is energy frontier • SLAC will support users at LHC • Exploration of the ‘Dark Universe’ • New models of user support by national labs • GLAST now • LSST, JDEM future SLUO 2008 Annual Meeting

  12. Electron Accelerator Science at SLAC • Core competency of the laboratory • Essential to future science strategy of the lab and the field • Our future science strategy depends on advances in electron accelerators • Both Photon Science and Particle Physics rely on advances in electron accelerator science SLUO 2008 Annual Meeting

  13. Users Organizations Going Forward • Both photon science and particle physics user communities are changing • BaBar and SSRL users couldn’t be more different • LCLS, LHC, GLAST, LSST users may find they have more similarities than differences • Opportunities to learn from each other • Culture for doing science is changing in all fields SLUO 2008 Annual Meeting

  14. Summary • SLAC is transforming to optimize for its future • Particle physics program high priority for lab going forward • Strong user support role essential to health and viability of particle physics at SLAC • Still working to optimize our role for the user community in this new era SLUO 2008 Annual Meeting
