1 Leveraging the SLAC Expertise Outlook and Strategy Tor Raubenheimer May 4, 2011

2 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? Leveraging the SLAC Expertise Page 2

3 Programmatic Elements and Future Directions Adv. Accelerator R&D: Microwave acceleration Plasma acceleration Laser acceleration FEL related R &D; FEL operation Storage rings Instrumentation High rep rate, ultrafast Accelerator Computations Pulsed Power Modulators BEAM DynamicsHigh Power RF Fully aligned with SLAC mission DOE fully funds 100% Unique capability @SLAC. DOE will partially fund Very useful for SLAC Largely funded through grants NC Linac Design & Construction Leveraging the SLAC Expertise Page 3

4 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 Leveraging the SLAC Expertise Page 4

5 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, … OHEP funding is expected to decrease significantly: ILC BES funding for Accelerator R&D will likely increase but not to cover the OHEP portion Leveraging the SLAC Expertise Page 5

20 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 Expertise Page 20

21 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 Expertise Page 21

22 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 Leveraging the SLAC Expertise Page 22
