Predictive modeling of pedestal structure in KSTAR using EPED model

Physics of Plasmas, 2013
A predictive calculation is given for the structure of edge pedestal in the H-mode plasma of the KSTAR (Korea Superconducting Tokamak Advanced Research) device using the EPED model. Particularly, the dependence of pedestal width and height on various plasma parameters is studied in detail. The two codes, ELITE and HELENA, are utilized for the stability

Tungsten pedestal structure for nanotriode devices

Journal of Vacuum Science & Technology B: Microelectronics and Nanometer Structures Processing, Measurement, and Phenomena, 2004
The nanotriode is a vacuum nanoelectronic device with a turn-on voltage for a field emission of ∼8 V, in which electrons are emitted from a metal nanotip with a radius ∼1 nm in an integrated vacuum chamber, over a distance of ∼100 nm. However, surface breakdown of the gate-cathode dielectric within the device chamber occurs ∼2 V outside of its ...

Investigation of edge pedestal structure in DIII-D

Physics of Plasmas, 2006
A 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. Luxon, Nucl.

Edge pedestal structure

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.

High-power broad-area laser diode performance improvement with a double pedestal structure

Japanese Journal of Applied Physics, 2019
We propose a novel heat-sinking structure for a high-power broad-area laser diode. In our laser diode, the pedestal structure is introduced to both top and bottom sides of the laser diode so that the heat generated within the device can be more ...

STRUCTURAL STUDY OF AN/FPS-24 PEDESTAL

1965
Abstract : 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.

Incorporation of a tungsten pedestal structure into the nanotriode device

IEEE/CPMT/SEMI. 28th International Electronics Manufacturing Technology Symposium (Cat. No.03CH37479), 2004
In 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.

Experimental Structural Analysis of Pedestal Mounted Stinger System Turret

Applied Mechanics and Materials, 2007
An experimental approach for the solution of the turret stress state and dynamic behavior has been presented using strain gages and accelerometers on Pedestal Mounted Stinger System. The critical stress locations were determined by finite element analysis outputs where rosettes are bonded in order to perform the life profile simulation tests.
