Introduction• SLAC has broad accelerator expertise
– Accelerator and accelerator systems design– Beam physics and computing– Advanced accelerator concepts– High power rf
• Historically funded on HEP– HEP funding for accelerator research is decreasing while BES
funding is increasing although less quickly• In this era of declining research funding, can we use WFO
to support the research infrastructure and personnel leveraging our capabilities?

WFO – What does it mean for us?• SLAC Accelerator research consists of two components:
– Fundamental research (PWFA, DLA, beam theory, …)– Accelerator design (LCLS-I/II, ILC, Super-B, LHC, …)
• Have focused on projects in which we have physics interest and frequently leadership and have focused research on concepts that might advance the mission physics
• Will need to apply our skills to a wider set of projects, some of which will expand the SLAC mission– Need to develop a PI culture and support the development of
proposals while balancing resources between WFO and main program

Present Funding Distribution• Present ARD funding is roughly 40M$ with 2.5M$ in WFO
at present. WFO includes Project-X, MAP, BNL, LLNL, CERN, SBIRs, US-Japan, …

SLAC Accelerator Expertise• Technical expertise across accelerators:
– RF structures, power sources and pulsed power– Diagnostics, feedback and timing/synchronization
• Innovative acceleration concepts– High gradient linacs with rf, lasers and plasma
• Systems design– Beam dynamics– Rf design and modeling– Linac systems design and modeling
• Component fabrication and test facilities to verify prototypesLeveraging the SLAC ExpertisePage 7
Fabrication Capability & Test Facilities• SLAC’s ability to conceive, design, build and test should be
attractive to collaborators and WFO agreements– Experienced shops able to build desired components– Extensive rf test capabilities and multiple accelerator bunkers
Leveraging the SLAC ExpertisePage 8
Linacs & Rf Components• High gradient linacs
– Being built with LLNL for MEGa-ray and may be proposed for ELI-NP gamma source, MARIE XFEL, ZFEL in Holland, ….
• Ultra-fast Electron diffraction– New designs may offer high resolution imaging capability
• Rf guns– LCLS S-band gun is world leading– Developing X-band guns for higher brightness & compact sources
• Rf specialty components– Harmonic rf linearizers are being built into LCLS-II, BNL ATF, Trieste
FERMI, PSI XFEL and likely PAL XFEL and SINAP soft x-ray source– Deflecting mode cavities provide longitudinal phase space
diagnostics for short bunches: LCLS, NLCTA, likely PAL XFEL, …

Structure Optimizations for MARIE• X-band structures are very efficient for short-pulse FEL’s
• MARIE requireslong-pulseoperationwith 1~1.5ms beams
• Studyingdifferentoptions

Hadron Radiation Facility• A new proton/ carbon ion radiation therapy center is being
developed as a Stanford/SLAC/UCSF/LBNL proposal– 200 M$ facility to be proposed as therapy and R&D center– Leverage SLAC accelerator expertise in the design, procurement
and operation of the facility

Advanced Technology Opportunities• Industrial and Medical accelerators
– Opportunities exist to apply new concepts to industrial or medical accelerators, e.g. high power L-band linac for sterilization or high gradient X-band proton linac for hadron therapy
• 3 DARPA proposals have been submitted in last few months– A Direct Laser Acceleration Compton source with Stanford Univ.– A compact X-band Compton source with LLNL– An all optical radiation source with UCLA

Existing Collaborations (I)• Working with Fermilab on Project-X
– Funding for rf cavity design, rf power system design, kicker systems– 400 k$ in FY11 on rf power but expect this to grow in FY12– Focused on solid-state rf technology which will have broad
application to high power linacs, light sources and rings• Working on Muon Accelerator Program
– 260 k$ in FY11 for rf cavity design and fabrication– Future work on collider ring & MDI and linac design & dynamics– Grow program to 2~3 M$/year
• Working with US LARP and CERN on LHC and HL-LHC– Many tasks: collimators, crab cavities, feedback, ring design– Funding probably remains constant as tasks evolve
Leveraging the SLAC ExpertisePage 16
Existing Collaborations (II)• Working with CERN on X-band structure design & testing
– Will help drive commercialization of X-band rf technology– Provide partial support SLAC test facilities (~200 k$/yr)
• Collaborating with LLNL on MEGa-ray Compton source– Building a test stand with rf gun in FY12– Buying components for 250 MeV linac (6 structures, 2 klystrons)– Working on accelerator physics, rf gun, rf systems– Roughly 1.2 M$ in FY11; expect to increase in FY12– Wrote DARPA proposal with LLNL with 7.2 M$ SLAC
• LANL on MARIE, a 50 keV XFEL– Initial studies of options for high gradient acceleration (S, C, X-
band)– Possible funding to continue studies in FY11 (~300k$)– Possible funding for design and hardware in FY12 and beyond
Leveraging the SLAC ExpertisePage 17
Existing Collaborations (III)• PSI XFEL and Trieste FERMI
– Working on X-band linearizers (~600 k$ apiece in FY11)– Helping them understand high gradient upgrades (~10 M$ / GeV)
• Shanghai, Pohang and IHEP– All have expressed interest in high gradient linacs for XFELs,
deflecting cavities for diagnostics, and linearizers• SciDAC
– Modeling rf cavities, breakdown, dark current, etc for different groups around the world (~200 k$ / year)
• ILC GDE– Been leading Linac System Design and Rf Power Sources since
2005 (~5 M$ / year); expecting this to drop to zero.– May be opportunities to continue efforts in some form

Additional Funding Opportunities• Known opportunities:
– DOE science labs and NNSA– International science labs– DARPA, DHS, NIH/NCI and industry
• Need to create program office to:– Help identify opportunities– Support proposal development and approval– Track performance and balance priorities across lab
• Need to establish a funding mechanism that supports program and allows development of new concepts– LDRD, WFO tax, OHEP core support, BES core support
Leveraging the SLAC ExpertisePage 20
Challenges of a Multi-program Effort• Gain experience developing proposals across AD
– Early Career Awards– SciDAC proposals– DOE reviews and supplemental funding
• Changing SLAC culture to pursue external funding– PI-ship options exist and will grow with encouragement– Opens new set of opportunities for research– Increase rewards for successful proposals
• WFO is a commitment by the laboratory– WFO programs need to be fully supported by laboratory– Commit to support for PI’s between proposals
• Developing a risk management plan for WFO
Leveraging the SLAC ExpertisePage 21
Summary• A strong WFO program is possible
– Have technology and expertise that is recognized and needed– Scale of topics identified thus far is ~60M$ over 5 years
• Must develop processes to identify opportunities and track performance– Use LDRD and other funding sources to help develop opportunities
• To be successful this must become primary focus many members of laboratory– Have the option of PI-ship now and will further develop the culture of
pursuing independent proposals
