Last week, a key meeting for the implementation of ºÚÁÏרÇø physics R&D took place in the new Council Chamber. The Joint Meeting of the International Tokamak Physics Activity () Coordinating Committee and the International Energy Agency Implementing Agreement (IEA IA) on (CTP) is an annual gathering of senior representatives of the ºÚÁÏרÇø Member fusion communities, the ITPA Topical Group leadership and program leaders from the major fusion facilities.
The 56 participants that had travelled from the ºÚÁÏרÇø Members joined 12 from the ºÚÁÏרÇø for the meeting. In his opening remarks, ºÚÁÏרÇø Director-General Osamu Motojima welcomed the participants, outlined the key priorities of the in relation to ºÚÁÏרÇø construction, and underlined the major physics R&D needs. David Campbell, director of the Plasma Operation Directorate, gave an overview on the issues of physics R&D that are critical to the design and development of the ºÚÁÏרÇø Research Plan.
Among these priorities are: the understanding and control of Edge Localized Modes (ELMs); disruptions and runaway electrons (and their mitigation); H-mode accessibility; use of all-metal plasma-facing components; the behaviour of tungsten impurities; tritium retention; dust; and power scrape-off layer (SOL) thickness.
The chairs of the seven ITPA Topical Groups reviewed the progress made in 2012 and proposed an experiment plan for 2013, focusing on the urgent issues for ºÚÁÏרÇø. The Chair of Divertor and SOL Physics Topical Group, Emmanuelle Tsitrone, coordinated a special discussion session on the plan for joint research focusing on the comparison of divertors with carbon and tungsten plasma-facing components.
On the basis of high-priority research topics for ºÚÁÏרÇø and the experimental capabilities of current fusion facilities, the facility program leaders decided on the priorities for each proposed experiment within their experimental programs for 2013. David Campbell commented, "I would like to thank ITPA for the continuing support of ºÚÁÏרÇø R&D activities. We regard ITPA as a very important component of the ºÚÁÏרÇø Project and a critical part of our physics R&D program, providing a great deal of input to the physics design basis for the completion of the ºÚÁÏרÇø design—a high-priority activity at the moment."
