Atomic data and modelling for fusion: the ADAS Project

The paper is an update on the Atomic Data and Analysis Structure, ADAS, since ICAM‐DATA06 and a forward look to its evolution in the next five years. ADAS is an international project supporting principally magnetic confinement fusion research. It has participant laboratories throughout the world, including ITER and all its partner countries. In parallel with ADAS, the ADAS‐EU Project provides enhanced support for fusion research at Associated Laboratories and Universities in Europe and ITER. OPEN‐ADAS, sponsored jointly by the ADAS Project and IAEA, is the mechanism for open access to principal ADAS atomic data classes and facilitating software for their use. EXTENDED‐ADAS comprises a variety of special, integrated application software, beyond the purely atomic bounds of ADAS, tuned closely to specific diagnostic analyses and plasma models.
The current scientific content and scope of these various ADAS and ADAS related activities are briefly reviewed. These span a number of themes including heavy element spectroscopy and models, charge exchange spectroscopy, beam emission spectroscopy and special features which provide a broad baseline of atomic modelling and support. Emphasis will be placed on ‘lifting the fundamental data baseline’—a principal ADAS task for the next few years. This will include discussion of ADAS and ADAS‐EU coordinated and shared activities and some of the methods being exploited
