The proceedings of the Eleventh APS Topical Conference on Atomic Processes in Plasmas benchmarks the ongoing research developments in the interdisciplinary interaction between atomic and plasma physicists as they tackle large scale applied research problems in magnetic fusion, x-ray lasers, astrophysics, inertial fusion, and materials processing.

All papers were peer-reviewed for this proceedings volume. The conference focused on atomic physics relevant to plasmas, and plasma science dependent on atomic processes, from either a modeling or diagnostics point of view. Also, an exciting breakthrough discovery was first announced at this conference on a new antihydrogen formation technique. Topics include the relatively mature research areas of atomic structure and collisions, atomic kinetics, laser-produced plasmas, magnetic- and inertial-confinement fusion, Z-pinches, opacities and equation of state, lighting, and astrophysics, as well as the burgeoning areas of warm dense matter simulations and ultracold plasmas used, for example, in the recent formation of antihydrogen.

The APS Topical Conference on Atomic Processes in Plasmas brings together researchers working in atomic physics and in plasma science, emphasizing the strong and synergistic overlap of these fields. The latest developments in atomic physics reported are recent advances in plasma science, such as in magnetic or inertial confinement fusion, Z-pinches, astrophysics, and technical plasma processing.

This volume of proceedings presents recent research in the areas of overlap between atomic and plasma physics. The activities of two international data centres are discussed.
