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…
