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

• 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

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

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

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

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

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

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
