Radial Electric Fields for Improved Tokamak Performance
… ash build-up in a TFTR-sized, fusing tokamak plasma is explored. In an idealized tokamak plasma, an externally-imposed radial electric field leads to plasma rotation, but no charge current flows across the magnetic fields. However, a realistically-low neutral density profile generates …

Multi-Tokamak Assessment of Modeled Temperature Profiles
… experimental data from three well-documented tokamak discharges: Holland (2011) [1], White (2014) [2], and Zagorski (2015) [3]. The validation study uses the iterative TRANSP and PORTALS transport solvers to achieve flux-matching and self-consistency between heat sources and transport. The …

Theoretical explanations of I-mode impurity removal and H-mode poloidal pedestal asymmetries
… problem while providing free fueling for optimum tokamak performance. High confinement mode operation was discovered 35 years ago to almost quadruple fusion power, and later explained by turbulence reduction by sheared flows. Less than a decade ago, improved mode operation was discovered to have …
