Overview

Atomic and molecular (A+M) processes have a central role in simulation and diagnostics of fusion plasma. Plasma-material interaction (PMI) processes determine the erosion rate and lifetime of plasma-facing materials. Plasma-material interaction in combination with material microstructure properties is the key to the hydrogen (tritium) inventory in walls. Therefore there is a continuing need for better understanding and improved data on A+M+PMI processes and properties in fusion devices and on relevant material microstructure properties.

On several occasions over the past 40 years the IAEA has organized meetings to review the status of A+M+PMI research for fusion, bring fusion scientists together with specialists in atomic, molecular and materials science, and develop an outlook on major A+M+PMI research and data needs to advance the cause of fusion energy. The first such meeting was held in 1976 at Culham Laboratory, UK, and formulated for the first time a comprehensive scope for A+M data needs for fusion. The second meeting was held in 1980 in Fontenay-aux-Roses, France, to review the status of data needs in relation to experimental programs of large tokamaks. The third meeting was held in Cadarache, France, in 1992 with the objective to review and identify new data needs for large operating fusion machines. The fourth meeting was held at the Jülich Research Centre, Germany, in 2002 to reconsider data needs in light of the further increase in size and power of fusion machines and the early use of deuterium-tritium fuel in these machines. With ITER now under active construction, with expanded interest in issues facing the next-step DEMO or fusion nuclear science facility (FNSF) as well as the current generation of long-pulse experiments, it seems appropriate to convene again a broad meeting on atomic, molecular and plasma-material interaction data for fusion science and technology.

Like the indicated earlier meetings the present meeting is meant to advance data-oriented research on A+M+PMI processes and properties that are important for fusion plasma simulation, fusion plasma diagnostics and fusion energy technology. As part of this goal, the meeting is meant to promote collaboration among fusion energy researchers and researchers in atomic, molecular and materials science, raise awareness in the A+M+PMI community of the continuing A+M+PMI science needs for fusion and highlight the contributions that can be made by the A+M+PMI sciences to fusion energy science and technology.

The meeting will feature invited and contributed oral presentations as well as a poster session. All talks are scheduled for 30 minutes including question time. An electronic projector connected to a computer with a slot for a USB flash drive or memory stick will be available for the presentations (PDF or Power Point).

In addition to the presentations there will be expert working sessions and discussion sessions dedicated to data research needs for A+M processes, PMI processes and materials structure properties.
