Twelfth Meeting of the ITPA Group on Diagnostics

The Twelfth Meeting of the ITPA Topical Group on Diagnostics was held at the Princeton Plasma Physics Laboratory (PPPL), USA, from 27 - 30 March 2007. ITPA stands for "International Tokamak Physics Activity", which aims at international cooperation in the development of the physics basis for burning plasmas in tokamaks. The meeting was opened by Professor Goldston, Director of PPPL, and was attended by 71 participants drawn from China, EU, Japan, the Russian Federation, Republic of Korea, USA, and the ITER International Team.

Special sessions were devoted to the identification of outstanding work needed in the field of irradiation effects on diagnostic components for ITER, on progress in the field of first mirror research and on a review of candidate diagnostic techniques for measuring confined and escaping alpha particles. Part of the ongoing ITER design review is an assessment of the integrated measurement capability. This will be carried out as a high priority topic over the next few months.
