Physics of Plasmas, 2004
The hypothesis is advanced and it is investigated that, in between or in the absence of edge-localized modes, the structure of the edge pedestal is determined by the transport requirements of plasma particle, momentum and energy balance, and by recycling neutral atoms.

The Research of EAST Pedestal Structure and Preliminary Application
Plasma Science and Technology, 2016The pedestal characteristic is an important basis for high confinement mode (H-mode) research. Because of the finite spatial resolution of Thomson scattering (TS) diagnostic on Experimental Advanced Superconducting Tokamak (EAST), it is necessary to characterize the pedestal with a suitable functional form.

STRUCTURAL STUDY OF AN/FPS-24 PEDESTAL
1965Abstract : Results are presented from an investigation of the load distribution to the main azimuth bearing of the AN/FPS-24 radar. The bearing is a 10-ft diameter 4-point contact bearing subjected to thrust, radial, and overturning loads. Actual static ball loads were determined in a field test.

Pedestal structure in H-mode plasmas
Nuclear Fusion, 2014The present understanding of edge pedestal structure is reviewed. Pedestal plasma strongly affects fusion power and divertor heat load, and as such, characterization of the pedestal structure has significantly progressed. In high-confinement mode (H-mode) plasmas, the pedestal component plays the role of a boundary condition in determining the core ...

Incorporation of a tungsten pedestal structure into the nanotriode device
IEEE/CPMT/SEMI. 28th International Electronics Manufacturing Technology Symposium (Cat. No.03CH37479), 2004In this paper, the nanotriode fabrication process has been modified to incorporate a pedestal for the nanopillars, which increases the dielectric surface leakage gap, whilst maintaining the extractor-nanopillar gap.

Investigation of edge pedestal structure in DIII-D
Physics of Plasmas, 2006A calculation based on the requirements of particle, momentum and energy conservation, conductive heat transport, and atomic physics resulting from a recycling and fueling neutral influx was employed to investigate the experimental density, temperature, rotation velocities, and radial electric field profiles in the edge of three DIII-D [J.

Prediction of DIII-D Pedestal Structure From Externally Controllable Parameters
IEEE Transactions on Plasma Science, 2021The sharp increase of pressure at the edge of a high confinement mode (H-mode) plasma, the pedestal, strongly impacts overall plasma performance. Predicting the pedestal is a necessity to control and optimize tokamak operations. An experimental data-driven machine learning (ML) approach is presented, which predicts the pedestal heights and widths of ...

Resonant magnetic perturbation effects on pedestal structure and ELMs
Nuclear Fusion, 2012Abstract The plasma transport processes by which externally applied resonant magnetic field perturbations (RMPs) mitigate or suppress edge-localized modes (ELMs) in low-collisionality tokamak H-mode plasmas are explored. Experimental data from DIII-D indicates the dominant RMP-induced transport occurs at the pedestal top where electron ...
