Objectives Background Where Registration Program Links

  • Inform the broader U.S. fusion community on current ITER plans and negotiation activities, and to engage them in ITER preparatory work.
  • Involve the community in ongoing technology and physics R&D relevant to Burning Plasma Physics and ITER. Physics is carried out through International Tokamak Physics Activity (ITPA).
  • Provide community input to the preparation of proposals for U.S. hardware contributions to ITER and for U.S. performance of ITER.
  • Begin discussion of ITER as a scientific and technological research opportunity.
Background Community forums have played essential roles in the development of U.S. strategy for undertaking a burning plasma experiment and the improvement of our understanding of the scientific and technical issues for the study of self-heated fusion plasma. Recently, the UFA sponsored two Burning Plasma Workshops (Austin, December 2000 and San Diego, May 2001 ) in preparation for the 2002 Fusion Energy Sciences Summer Study held at Snowmass. This provided crucial community input to the the long-range planning activities of the DOE and FESAC and culminating in the FESAC Burning Plasma Strategy Panel Report "A Burning Plasma Program Strategy to Advance Fusion Energy " in September 2002.

The U.S, joined the ITER negotions, as announced by by the Secretary of Energy on January 30 and President Bush on February 6, 2003. A U.S. delegation attended the 8th. ITER negotiation meeting held at St. Petersburg, Russia on February 18-19, 2003. A series of meetings, involving ITER Parties, are being organized as part of the Negotiations forat in Toronto on April 8-17, 2003 to deal with management and administrative issues. These ITER related meetings are expected to be held every two months or so in preparation for decisions on ITER siting, construction, procurement allocations, and on cost sharing.

On March 4, the Dr. Anne Davies of the DOE Office of Fusion Energy Sciences wrote (an open letter) to ask Dr. Ned Sauthoff to serve as the U.S. ITER Planning Officer with Dr. Charles Baker, as his deputy, and to form a multi-institutional working team of people from around our program to assist the OFES in meeting the many needs associated with U.S. ITER preparations. A national Burning Plasma Program Advisory Committee (BPPAC) has been formed, chaired by Prof. Stewart Prager, to strengthen community involvement in ITER Planning Office.

This U.S. ITER Forum is the first community workshop organized to provide input to ITER preparations and to better inform U.S. scientists and engineers how they might particpate in ITER

"Kick-off Speakers"…

Friday, 9 May 2003

8:30 Break-out discussions:

Forum participants will discuss within small groups and suggest answers to the question:

  • What factors should be considered when developing the U.S. negotiating strategy for ITER?

Forum participants will form two breakout groups to discuss top-level answers to this question. A guide to the discussion questions is available here. Individuals who would like to make short statements within their breakout groups should prepare a one-slide comment and notify a member of the Organizing Committee:

  • "Blue Group": Stan Milora (Discussion Leader), Cary Forest (Reporter), Raffi Nazikian (Scribe)
  • "Yellow Group": Réjean Boivin (Discussion Leader), Joe Snipes (Reporter), Mike Mauel (Scribe)
