The data center at Oak Ridge National Laboratory (ORNL) has compiled, collected, evaluated, recommended, and disseminated atomic, molecular, and particle-solid collision data for more than forty years, serving a broad range of plasma science applications, most notably, fusion energy research. I will describe the ongoing activities of the ORNL Controlled Fusion Atomic Data Center (CFADC) in this presentation to illustrate both the directions we are pursuing in data production and evaluation as well as in dissemination of this data.

In particular, I will highlight recent and ongoing work to apply state-of-the-art methods of calculation to production of comprehensive databases of collision cross sections needed in fusion energy research focusing on such issues as the boundary and edge physics, divertor simulation, neutral beam heating, and diagnostics. I will also describe briefly new work that is synergistic with these activities that is opening up new capabilities through an upgrade to the ORNL Multicharged Ion Research Facility, enabling novel studies of ion-atom/molecule, electron-ion, and particle-surface interactions and providing critical benchmarks for our theoretical data production. Finally, an ongoing project carried out in close collaboration with researchers at the National Institute for Standards and Technology and the International Atomic Energy Agency to develop an XML standard and dialect for the exchange of atomic and molecular data will be described.

The CFADC is supported by the U.S. Department of Energy, Office of Fusion Energy Sciences, and is a collaboration involving ORNL staff members, Predrag Krstic, Fay Ownby, Mark Bannister, Charles Havener, and Fred Meyer, and a network of expert consultants including Ed Thomas, Brian Gilbody, Mitch Pindzola, Thomas Morgan, Phillip Stancil, and Tatsuya Minami.
