Technical Summary of the First U.S. Plasma Jet Workshop

This paper provides a technical summary of the first U.S. Plasma Jet Workshop, which was sponsored by the DOE Office of Fusion Energy Sciences and held at Los Alamos National Laboratory on January 24–25, 2008. The purpose of the workshop was to bring together members of the national plasma jet research community in order to discuss ongoing research and identify research needs and opportunities in plasma jets and their applications, which include fundamental studies of high energy density (HED) plasmas, magneto-inertial fusion (MIF), laboratory astrophysics, and disruption mitigation and fueling for magnetic confinement devices. Over the course of the workshop, about equal time was devoted to short technical talks and group discussions.
