Investigation of Core Transport Barriers in DIII-D Discharges with off-axis Te Profile Peaks
Ruifeng Xie, Max E. Austin, Kenneth W. Gentle +1
DIII-D discharges that transition to H-mode solely with off-axis electron cyclotron heating (ECH) often exhibit strong off-axis peaking of electron temperature profiles at the heat…
Investigating shear flow through continuum gyrokinetic simulations of limiter biasing in the Texas Helimak
Tess N. Bernard, Timothy Stoltzfus-Dueck, Kenneth W. Gentle +3
Previous limiter-biasing experiments on the Texas Helimak, a simple magnetized torus, have been inconclusive on the effect of flow shear on turbulence levels. To investigate this,…
Gyrokinetic continuum simulations of plasma turbulence in the Texas Helimak
Tess N. Bernard, Eric L. Shi, Kenneth Gentle +4
The first gyrokinetic simulations of plasma turbulence in the Texas Helimak device, a simple magnetized torus, are presented. The device has features similar to the scrape-off laye…
The deteriorating effect of plasma density fluctuations on microwave beam quality
Alf Köhn, Max E. Austin, Michael W. Brookman +13
Turbulent plasma edge density fluctuations can broaden a traversing microwave beam degrading its quality. This can be a problem for scenarios relying on a high spatial localization…
Turbulence driven particle transport in Texas Helimak
Dennis L. Toufen, Zwinglio O. Guimarães-Filho, Iberê L. Caldas +2
We analyze the turbulence driven particle transport in Texas Helimak (K. W. Gentle and Huang He, Plasma Sci. and Technology, 10, 284 (2008)), a toroidal plasma device with one-dime…
