Abstract Text:
In many present and future fusion devices, the details of device geometry and its components (eg. structural supports) can have a significant impact on the dynamics present within the plasma - even if the plasma itself is nominally axisymmetric. These considerations, along with coupling the relevant physics in these different regions, challenge the development of models necessary to design and control magnetized plasmas; a necessary feature for engineering future commercial fusion devices. This poster will describe work to develop a set of predictive modeling tools for plasma dynamics in devices with important 3D structural features through closely coupled experimental and theoretical investigations. Active projects to be discussed include: 1) experimental investigation and model validation of large-scale self-organization in continuously driven plasmas in the HIT-SI family of experiments [1,2], 2) the development and validation of 3D multiphysics tools for predictive first-principles modeling of plasma-wall coupled dynamics [3,4] and 3) accurate reconstruction of plasma equilibria in the presence of eddy current-induced 3D error fields [5]. This research program is supported by US Department of Energy awards DE-SC0021325, DE-SC0019239, and DE-AR0001266 and by CTFusion, Inc. under DOE award DE AR0001098.
