Investigation of the shear layer versus the last closed flux surface on TEXT-upgrade
… Tokamak Upgrade (TEXT-Upgrade) has a set of 41 magnetic sensor coils that are used to determine the magnetic flux surface configuration of plasma discharges. These reconstructions include the x-points and the separatrix. These magnetic flux surface reconstructions and simultaneous data from …

The solar corona: modeled, discretized, visualized
… corona---the plasma that extends from the solar surface into space. These coronal fibers can be modeled as magnetic filaments whose shape is governed by the magnetohydrostatic equation. The first goal of this dissertation is to rigorously establish and derive the mathematical model to solve this …

Discontinuous Galerkin modeling of plasma turbulence in a simple magnetized torus
… of a sheared cylinder and, with simple magnetic geometry and extensive diagnostics, are useful for validating numerical models. With helical, open field lines and magnetic shear, the Helimak is a good model of the plasma turbulence in the scrape-off layer (SOL) region of tokamaks or …

Plasma flows in the Alcator C-Mod scrape-off layer
… of tokamaks, at locations far from material surfaces. Ballooning-like transport asymmetries are thought to be a principal driver for the strong parallel flows, a hypothesis supported by the observation of steep high-field side pressure profiles in double-null discharges. Yet parallel flow can …

Rotation studies in fusion plasmas via imaging X-ray crystal spectroscopy
… with turbulence suppression via flow shear in magnetically confined fusion plasmas has been well documented. Currently, the standard methods for both generating and measuring plasma rotation involves neutral beam injection (NBI). In the large, high density plasmas envisaged for next generation …

Experimental and computational magnetic surface mapping of the HIDRA stellarator
… interaction experiments. Its particle and heat fluxes should be high enough to test and develop novel plasma facing components, with a main focus on liquid lithium designs such as the FLiLi (Flowing Liquid Lithium) and the LiMIT (Liquid-Metal Infused Trenches) concepts. With the planning of new …
