Description

The DOE SC program in Fusion Energy Sciences (FES) hereby announces its interest in receiving grant applications for collaborative research on the National Spherical Torus Experiment Upgrade (NSTX-U) at the Princeton Plasma Physics Laboratory, as well as other international and domestic spherical tokamak facilities. This FOA will be one of two accepting applications for research pertaining to spherical tokamaks in Fiscal Year 2020. Only applications for collaborative research on international and domestic spherical tokamaks should be submitted to this FOA. Applicants may wish to search for DE-FOA-0002255 to see the details of the other FOA supporting research in spherical tokamaks.The Spherical Tokamak program helps to build the scientific foundations for fusion energy by both contributing to the fundamental understanding of magnetically confined plasmas and assessing the attractiveness of the spherical tokamak for future fusion facilities. Applications for collaborative research must support the Spherical Tokamak program by addressing key scientific issues related to one or more of the following topics: Macroscopic Stability, Multi-Scale Transport Physics, Plasma Boundary Interfaces, Plasma Waves and Energetic Particles, and Advanced Operating Scenarios and Control.
