Introduction David Swain ITER International Team ITER-US-EU ICRF Antenna Planning Meeting Garching October 13 -14, 2004 DWS- US-EU ITER antenna mtg 10 -04 1 ITER

Why are we here? A deep philosophical question, but we’ll be more limited in this meeting Long-range goal: Deliver an antenna for ITER that meets the requirements and operates reliably Goal of this group: Coordinate the work of the US and EU, with the guidance of the IT, to carry out a program of design, R&D, fabrication and testing to meet the long-range goal.

At this meeting, we hope to: Review the present EU and US ICRF R&D programs Look at a proposed schedule for ITER, with emphasis on the ICRF antenna – Comment on and revise if needed Discuss the antenna conceptual design options to consider. List the issues/questions for each concept List the R&D that we think will be needed to select among the different antenna options, and to provide assurance that the one chosen will work. Discuss selection criteria Begin to lay out a coordinated design and R&D plan. DWS- US-EU ITER antenna mtg 10 -04 3 ITER

Antenna delivery to ITER From discussions with Barabaschi, delivery of antenna to ITER site 12 months before first plasma seems reasonable Delivery to ITER site: June 30, 2014 This assumes that antenna will have been: Assembled off-site Tested off-site – Pumped down and checked for leaks – Thermal cycling corresponding to bake-out, etc. – Measurement of all rf antenna parameters – High-power (i. e. , high current and voltage) rf testing in vacuum – Long-pulse rf testing to look for long-pulse heating/outgassing – …… Needed modifications can be done at off-site assembly and testing location Antenna will be shipped to ITER site and then run through some tests (TBD) to check for shipping damage DWS- US-EU ITER antenna mtg 10 -04 5 ITER

Antenna schedule for June 2004 delivery DRAFT Need to have antenna concept chosen and most R&D completed, by Dec. 2007. DWS- US-EU ITER antenna mtg 10 -04 6 ITER
