Compositions and chemical states on the co-deposition layer of lithiated tungsten of plasma-facing components of EAST

Nuclear Materials and Energy, 2017
Lithiation is beneficial to enhance plasma performance in EAST by reducing hydrogen and impurities recycling via lithium (Li) wall conditioning. High-Z materials like tungsten (W) have been selected as up–divertor in EAST tokamak.

Thermal damage detection of EAST internal component based on machine learning

Machine Learning: Science and Technology
During the discharge process, thermal events are common and destructive in Tokamak experiments. High energy particles in plasma can collide with device components such as limiters and diverters, which can lead to overheating, material cracking, and even ...

Calculation of in-situ steady-state heat flux on EAST lower divertor

Nuclear Materials and Energy
Heat flux is a key issue in tokamak devices. The non-uniform high heat flux on Plasma-Facing Components (PFCs) has led to local severe damage, including cracks and melting, in current tokamaks such as EAST and WEST.

Particle acceleration by circularly and elliptically polarised dispersive Alfven waves in a transversely inhomogeneous plasma in the inertial and kinetic regimes

, 2011
Dispersive Alfven waves (DAWs) offer, an alternative to magnetic reconnection, opportunity to accelerate solar flare particles. We study the effect of DAW polarisation, L-, R-, circular and elliptical, in different regimes inertial and kinetic on the ...

SPECTRA ANALYSIS OF RUNAWAY ELECTRON SYNCHROTRON RADIATION FOR THE RECENT EAST RUNAWAY EXPERIMENT

East European Journal of Physics, 2017
The energy of disruption generated runaway electrons can reach as high as tens of megaelectronvolt and they can cause a serious damage of plasma-facing-component surfaces in large tokamaks like International Thermonuclear Experimental Reactor (ITER). The
