First Experimental Evidence of Helicon Current Drive
J. B. Lestz, R. I. Pinsker, B. Van Compernolle +10
Helicon current drive is an attractive solution for driving current to sustain steady state tokamak operation in reactor conditions. Dedicated DIII-D experiments have been conducte…

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…

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…
