11. 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

12. FESAC Panel needs our help FESAC Panel established – Martin Greenwald Chair • Needs information on international facilities • Program objectives • Capabilities • Plans • 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
