Lab Overview and Future Onsite Facilities

1. Lab Overview and Future Onsite Facilities Persis S. Drell Director SLAC FACET Review

2. SLAC: The Lab is Changing • SLAC’s research vision is evolving dramatically. • The balance and content of the scientific foci is changing in substantial ways • Photon science is rapidly expanding • After the B-factory turns off later this year, the major on-site accelerator-based facilities will be primarily serving photon science • A growing accelerator R&D effort will fuel future upgrades & new facilities • Particle Physics and Astrophysics • Will be based on program of accelerator-based, non-accelerator and particle astrophysics experiments • No longer be centered on an in-house HEP accelerator facility, requiring re-invention of our national laboratory role • Mid-term and long-term accelerator research will also be a continuing emphasis and strength of the program • A continued vigorous program of accelerator research is an extremely high priority for the laboratory • Essential investment for future of HEP and BES programs FACET Review

3. Accelerator research directions • Mid-term: broad strategy for achieving the goal of a TeV electron-positron collider • Leader on the development of the RDR for the ILC and continuing leadership in many of the technical systems, • Expanding a program of high-gradient research to include new x-band power sources as part of a collaboration with the CLIC program at CERN • Long-term: Fundamental research in entirely new directions for acceleration techniques • Develop a basic understanding of ultra-high gradient acceleration techniques, including plasma-wakefield, dielectric wakefield, and lasers • Aimed at development of transformational technologies as the basis for reaching the very high energies demanded by particle physics FACET Review

4. Accelerator research directions • Upgrades and new directions for the x-ray FEL program • Facilities for exploring enhanced self-amplified spontaneous emission • Electron source R&D for next generation light sources • Studies of collective effects, including space charge and coherent synchrotron radiation modeling • Exploration of rf cavities as beam modulators • Exploratory studies of ultrashort “single-spike” operation of FELs • Opportunities for ultra-high intensity synchrotron sources • World-class facilities are the basis for these R&D directions • FACET will be unique in providing high-power beams to enable far-field development of new ultra-high gradient techniques FACET Review

5. LCLS: Linac Coherent Light Source SLAC ACCELERATOR FACILITIES Turn-on in 2009: LCLS will be the World’s First X-ray Laser FACET FACET Review

6. Hadron Production Facility FACET Project FACET project consists of four elements: • Accelerator Science Facility (ASF) (Sector 20) • e+ bunch compressor (Sector 10) • Electron Bypass Line (EBL) extension to ESA • Hadron Production Facility in A-Line to ESA FACET Review

7. Accelerator Complex is Evolving • LCLS Program • Currently in construction • Capability for early science in late FY09 • Completion of project construction in FY10 • Operations of 1/3 of linac (120 Hz operations) plus LCLS injector, undulator and controls systems; 4 experiments • SSRL Program • SPEAR3 operations and scientific programs • PPA Program • Particle and particle astrophysics scientific programs off site • Accelerator Research on site • Operations of FACET and NLCTA facilities FACET Review

8. Business Model • BES Primary Stewardship • BES Supports Linac Ops (1/3 of Linac) • BES Supports Linac Maintenance (full Linac) • BES covers org costs and direct program support costs for Linac related accelerator operations: includes all major technical infrastructure at the laboratory essential to accelerator operations • Klystron, CPE, CEF, Scientific Computing Infrastructure • HEP accelerator based programs (FACET, NLCTA, ILC) leverage off BES base • Significant uncertainty in HEP use of core technical infrastructure (i.e. ILC) • Success of LCLS cannot depend on future of HEP funding to these departments • HEP and BES share site-wide indirect costs • This model ensures that operations support for LCLS will not be dependent on future HEP programs (e.g. ILC) FACET Review

9. Operations Post 2009 • SLAC has defined its operating scenario for FY09 and beyond • Detailed review by BES has endorsed the proposed model and funding level • Budgeting and accounting structures in place to manage the transition • The business model and funding level provides an opportunity: • A forefront accelerator R&D program can leverage off the BES investment • Allows experimental program (HEP & BES) that utilizes unique beams FACET Review

10. Future Development of the Accelerator Complex • Active discussion of strategic future of major elements of SLAC accelerator complex • Focused on light sources • Upgrades to LCLS 1 • LCLS 1.5 • 2nd undulator: soft x-ray • Hope for 2011 or 2012 start • LCLS 2 • Higher energy • Would use at least 2/3 of linac • Interferes with FACET • Timescale ‘not before 2015’ • Time early probably 2017-2018 • Requires gun development to become a reality FACET Review

11. Future Development of the Accelerator Complex • PEP 2.5 • Add beamlines to existing ring • Unique SR source leveraging of HEP investment in PEP-II • Very early stages of discussion • Timeline???? • As BES ramps up investments in accelerator R&D, SLAC will strive to broaden accelerator research program • Now delayed until 2009 FACET Review

12. Summary • SLAC in time of transition • Dramatic changes from past • Exciting opportunities for the future • SLAC has defined its operating scenario for FY09 and beyond • Detailed review by BES has endorsed the proposed model and funding level • FACET an important element of continued rich and diverse accelerator research program at the lab • Unique facility for accelerator research FACET Review
