SLAC Accelerator Development Program

1. SLAC Accelerator Development Program Tor Raubenheimer OHEP Accelerator Development Review January 24-26, 2011

2. SLAC Accelerator Development • SLAC GAD program supports developing accelerator concepts before project funding is available • Accelerator design: FACET, End Station Test Beam, Super-B, … • LHC acc. research: LLRF, e-cloud feedback, crab cavity, … • X-band rf development: power sources, CLIC collaboration, … • Funding of roughly 4M$ per year • Excellent program with quantifiable results • Highly leveraged effort attracting additional funding • FACET and ESTB became OHEP funded projects • Many SLAC LHC GAD proposals now funded by LARP • Substantial SLAC LDRD and WFO funding • Attracting many collaborators • ~70 papers over the last two years SLAC Accelerator Development Program Page 2

3. Ongoing SLAC GAD Programs • Reports on main ongoing programs during GAD review: • LHC accelerator research Tom Markiewicz • Super-B accelerator design Michael Sullivan • X-band power source development Michael Fazio • X-band applications Chris Adolphsen • High performance rf modeling Arno Candel • Future plans • Transitions are happening in LHC and Super-B programs  have reduced FY11 budgets while developing future plans • X-band rf technology program is increased to commercialize components and complete additional testing beamline • Developing separate more expansive X-band rf technology development proposal in support of linear colliders and FELs SLAC Accelerator Development Program Page 3

4. Other SLAC GAD Programs • End Station Test Beam project • Funded in FY11 from Detector R&D B&R: 1.6M$ construction plus 0.4M$/year operation • FACET project • Funded in FY10 from ARRA and AIP: ~20M$ construction plus 6M$/year operation from Accelerator Science B&R • CLIC R&D • R&D largely being supported with CERN funds in FY11 • Project-X R&D • R&D directly supported by direct Fermilab funding in FY11 • Feedback and LLRF R&D • Ongoing support of 0.5 FTE to consider next generation technology SLAC Accelerator Development Program Page 4

5. Spending for SLAC GAD Program FY08 data not shown due to transition after December 2007 Omnibus Bill *A LHC funding in FY11 is primarily supporting students *B Additional support for Super-B design from LDRD funds in FY09-FY10; additional funding in FY11 possible from INFN and/or KEK. *C Klystron funding includes construction of an XL-4 and 1500k$ for commercial XL-4’s in FY11 *D Additional support for X-band program (rf gun) from LDRD funds and WFO from LLNL *E End Station Test Beam construction and operation are funded separately in FY11 *F FACET was funded by ARRA and OHEP AIP funds in FY10 and FY11 *G CLIC efforts supported through WFO funding from CERN in FY11 *H Project-X R&D is funded directly by Fermilab in part of FY10 and all of FY11 SLAC Accelerator Development Program Page 5

6. LHC Accelerator Research Future • SLAC has contributed many projects to LHC and LARP • Presently 5 main programs: • Present program is largely funded by LARP • SLAC may contribute to EU program on High Luminosity Large Hadron Collider Design Study (HL-LHC-DS) • Focus on: • storage ring nonlinear dynamics and collective effects • crab cavity design • Would maintain core competency in storage ring design and rf design • Uncertainty due to Super-B program and crab cavity specifications SLAC Accelerator Development Program Page 6

7. Super B-factory Future • SLAC contributed strongly to INFN B-factory design • INFN Super-B project was approved by the Italian gov. • However, OHEP had decided not to support the INFN project • Funds are available to transfer PEP-II hardware to INFN • Further studies or development could be supported by INFN • Decision may be revisited once INFN project team is formed • OHEP will support the Super-KEKB project • Opportunities for collaboration with KEK • Super-B program at SLAC is on hold while we decide on a path forward with either KEK or INFN • Project funding might begin in FY13 • Expect minimal GAD funding in FY11 but possible restart in FY12 SLAC Accelerator Development Program Page 7

8. X-band RF Technology Development • SLAC pioneered the X-band rf technology in 1990’s & 2000’s • Option for high gradient, compact linacs • High rf frequency and field gradients useful for beam manipulation • Long-term goal  provide an option for a linear collider • Collaborating with CERN on staged approach to CLIC • Short-term goal  wider use of technology • Near-term applications will facilitate technology adoption • Biggest obstacle to adoption is lack of vendors • Working with users & vendors to commercialize klystrons & structures • X-band rf technology GAD program bridges ‘valley of death’ • Develop and commercialize the best components from the existing technology suite and results from the US High Gradient Collaboration SLAC Accelerator Development Program Page 8

10. Summary • SLAC GAD program was has been focused since FY09 • Aimed at near-term development (5-10 years) and proto-projects • Many design efforts have become funded projects • Developing and commercializing X-band rf technology • SLAC GAD program has been very successful • Highly leveraged effort attracting additional funding and collaborators • Developed a number of proto-projects until funded • Produced ~70 papers in last two years • Program is focused on X-band rf in FY11 while LHC and Super-B plans are developed • Commercialize rf power source and work with collaborators to establish technology base SLAC Accelerator Development Program Page 10
