Diagnostics for first plasma study on EAST tokamak

Physics Letters A, 2008
Abstract The first plasma was obtained in the EAST on September 26th, 2006. Single-null (SN) and double-null (DN) diverted plasmas were achieved successfully in the EAST tokamak on January 22nd, 2007. The employed plasma diagnostics for first plasma study of EAST are as follows: a vertical one-channel far-infrared (FIR) hydrogen cyanide (HCN) laser ...

Design and Analysis of the Thermal Shield of EAST Tokamak

Plasma Science and Technology, 2008
EAST (Experimental Advanced Superconducting Tokamak) is a tokamak with superconducting toroidal and poloidal magnets operated at 4.5 K. In order to reduce the thermal load applied on the surfaces of all cryogenically cooled components and keep the heat load of the cryogenic system at a minimum, a continuous radiation shield system located between the ...

Online Plasma Shape Reconstruction for EAST Tokamak

Plasma Science and Technology, 2010
An online plasma shape reconstruction, based on the offline version of the EFIT code and MPI library, can be carried out between two adjacent shots in EAST. It combines online data acquisition, parallel calculation, and data storage together. The program on the master node of the cluster detects the termination of the discharge promptly, reads ...

Observation of Pedestal Plasma Turbulence on EAST Tokamak

Plasma Science and Technology, 2013
Pedestal plasma turbulence was experimentally studied by microwave re∞ectometry on EAST tokamak. The characteristics of edge pedestal turbulence during dithering L-H tran- sition, ELM-free H-mode phase and inter-ELM phase have recently been studied on EAST. An edge spatial structure of density ∞uctuation and its dithering temporal evolution is observed

Modeling of ICRF Antenna Coupling on East Tokamak

2018 IEEE International Conference on Plasma Science (ICOPS), 2018
Radiofrequency wave in ion cyclotron range of frequency (ICRF) is an important way for heating plasma, driving current and implementing plasma control in the magnetic fusion devices such as EAST and ITER tokamak. Achieving good coupling of ICRF power into the plasma is an essential issue for high power ICRF injection on the EAST tokamak.

Spectroscopic Measurements of Impurity Spectra on the EAST Tokamak

Plasma Science and Technology, 2012
Ultraviolet (UV) and visible impurity spectra (200~750 nm) are commonly used to study plasma and wall interactions in magnetic fusion plasmas. Two optical multi-channel analysis (OMA) systems have been installed for the UV-visible spectrum measurement on EAST. These two OMA systems are both equipped with the Czerny-Turner (C-T) type spectrometer.

Comparison between EAST and ITER tokamak

Theoretical and Natural Science
This paper provides an overview of nuclear fusion, which is considered as an ideal energy source for the future, with emphasis on its theoretical foundation and tokamak device. In nuclear fusion, the mass of products is always less than the mass of reactants, and this “mass defect” is converted into enormous released energy.
