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…
The effects of kinetic instabilities on the electron cyclotron emission from runaway electrons
Chang Liu, Lei Shi, Eero Hirvijoki +4
In this paper we show that the kinetic instabilities associated with runaway electron beams play an essential role for the production of high-level non-thermal electron-cyclotron-e…
Resolving ECRH deposition broadening due to edge turbulence in DIII-D by heat deposition measurement
Michael W Brookman, Matthew B Thomas, Jarrod Leddy +7
Interaction between microwave power, used for local heating and mode control, and density fluctuations can produce a broadening of the injected beam, as confirmed in experiment and…
Resolving ECRH deposition broadening due to edge turbulence in DIII-D by 3D full-wave simulations
Matthew B Thomas, Michael W Brookman, Max E Austin +5
Edge plasma density fluctuations are shown to have a significant effect on the electron cyclotron resonance heating (ECRH) beam in the DIII-D tokamak. Experimental measurements of…
Oblique electron-cyclotron-emission radial and phase detector of rotating magnetic islands applied to alignment and modulation of electron-cyclotron-current-drive for neoclassical tearing mode stabilization
F. Volpe, M. E. Austin, G. Campbell +1
A two channel oblique electron cyclotron emission (ECE) radiometer was installed on the DIII-D tokamak and interfaced to 4 gyrotrons. Oblique ECE was used to toroidally and radiall…
