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…
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…
Kinetic study of plasma current start-up under EBW power in tokamak plasmas
Erasmus J. du Toit, Martin R. O'Brien, Roddy G. L. Vann
Tokamak plasma current start-up assisted by Electron Bernstein waves (EBW) has been demonstrated successfully in a number of experiments. The dynamic start-up phase involves a chan…
Synthetic aperture microwave imaging with active probing for fusion plasma diagnostics
Vladimir F. Shevchenko, Roddy G. L. Vann, Simon J. Freethy +1
A Synthetic Aperture Microwave Imaging (SAMI) system has been designed and built to obtain 2-D images at several frequencies from fusion plasmas. SAMI uses a phased array of linear…
