Accelerator Physics at Accelerator Physics at NSFNSF

• Physics Division is committed to advancing the frontiers of accelerator physics, e.g., NSCL, ERL (with DMR, CHE, OMA), ILC damping ring (with DOE-HEP), plasma wake-field acceleration, and other technologies. $10M investment in FY08

• Division of Materials Research is the steward of two University-based Synchrotron X-ray Light Source Facilities (CHESS and SRC) and supports R&D for future coherent light sources. $12M investment in FY08

• Next-generation coherent light sources will be under consideration among future MREFC projects across NSF

Understanding NSF’s Role in Understanding NSF’s Role in Providing Frontier FacilitiesProviding Frontier Facilities

• NSF supports universities to advance the frontiers across science and engineering disciplines

• A major emphasis is on the integration of education and research to develop technical leaders

• NSF is committed to providing major frontier facilities broadly, across its programs, from research vessels to telescopes to gravitational wave detectors, via an NSF-wide MREFC activity

• Partnerships are sought in the development of all major facilities

II. R&D

III. Education

MPS Advisory Panel on Light Sources, Report Accepted by MPS Advisory Committee Nov. 2008, with Main Recommendations:

• NSF must play a stewardship role in a University based 4th generation light source• It must reflect the breadth of the science and engineering• NSF must therefore involve multiple Directorates and Divisions, and partnership with other agencies

I. MREFC

Continue active user research programs where next-generation light source R&D work is being pursued

NSF has a unique education and training role

Issues and ChallengesIssues and Challenges

• Accelerator Physics Drivers: HEP and/or light sources?

• Education/training vs user facilities

• Multi-disciplinary: both drivers & users

• Inter-agencies

• International – US plan?
