Evolution of radial force balance and radial transport over L-H transition
Understanding of plasma confinement modes is an essential component in development of a fusion reactor. Plasma confinement directly relates to performance of a fusion reactor in terms of energy replacement time requirements on other design parameters. Although a variety of levels of confinement …

Rotation studies in fusion plasmas via imaging X-ray crystal spectroscopy
… are identified; intrinsic rotation in enhanced confinement modes, lower hybrid wave induced rotation and ICRF mode conversion flow drive. Each of these methods is discussed in detail with reference to how they might be used in next generation tokamaks.

Investigation of Multi-Z Impurity Transport in Tokamaks using Neural Networks
… from synthetic fluxes generated for L, H, and I confinement modes in Alcator C-Mod, DIII-D, and ASDEX-Upgrade. To reduce training complexity, shot data are discretized by radius, and networks are developed at six ρ coordinates: 0.2, 0.4, 0.6, 0.7, 0.8, and 0.9. Fifteen plasma parameters are …

Understanding the Mechanisms that Determine the Edge Electron Density Profile in Tokamaks
… forming the so-called “pedestal" in the high-confinement mode (H-mode) in response to increased ionization. This phenomenon is found to be associated with changes to local particle transport, and is observed to be correlated with a local parameter governing the influence of turbulence from …
