US FES Program budget is increasingo American Competitiveness Initiative – double funding for

physical sciences in 10 years• Competition between three agencies

– DOE – Office of Science– National Science Foundation– National Institute of Science and Technology

o FES Budget increases in FY 2007 and FY 2008– New funding for ITER Project– DIII-D, C-MOD, NSTX operating 12-15 weeks annually– NCSX construction is progressing– Joint OFES – NNSA Program on High Energy Density Laboratory

A new charge from Dr. Ray Orbach to Fusion Energy Sciences Advisory Committee

• To assist for planning for the ITER era, it is critical that FESAC identify the issues arising in a path to DEMO, with ITER as a central part of that effort. Therefore, I ask FESAC 1) to identify and prioritize the broad scientific and technical questions to be answered prior to a DEMO; 2) assess available means (inventory), including all present and planned facilities around the world, as well as theory and modeling, to address these questions; and 3) identify research gaps and how they may be addressed through new facility concepts, theory and modeling.

• This is the first of two charges to FESAC – a second charge will be issued asking FESAC to develop a long-term strategic plan

FESAC Panel needs our helpFESAC Panel established – Martin Greenwald Chair

o Needs information on international facilities– Program objectives– Capabilities– Plans

o Proposal: IEA Tokamak Agreements Update ITPA/IEA Facility Information on tokamaks– Prepared by Otto Gruber in 2005– Most international tokamaks are represented in the

tokamak agreements
