Heavy Particle Collision Data for Fusion and Astrophysics

Abstract

A wide range of applications, for example, diagnostics and modeling of fusion plasmas, interpretation of astronomical observations and modeling of astrophysical environments, and simulation of material processing plasmas, require large, accurate, and complete collections of data for electron, photon, heavy particle, and surface interactions. Consequently, over several decades, experimental and theoretical efforts have been developed in order to measure or to calculate such data, and to synergistically explore the fundamental physical mechanisms that underlie interactions at the atomic scale. The present report illustrates some of the recent progress in development of techniques and their use in describing heavy particle collisions, in particular, those involving ions interacting with atoms and simple molecules, with specific applications of the resulting data in fusion energy research and astrophysics.
