Status of ECRH Project on EAST Tokamak
AIP Conference Proceedings, 2014A 140GHz electron cyclotron resonance heating and current drive (EC H&CD) project for EAST Tokamak is launched in 2011 with a total power of 4MW and pulse length of 100 s. The main objectives of the system are to provide central H&CD, assist start-up and control of MHD activities.

Thermal analysis of the EAST tokamak
Fusion Engineering and Design, 2021Abstract The superconducting magnet of the Experimental Advanced Superconducting Tokamak (EAST) will experience large steady-state and transient heat loads during operation, which is undoubtedly a major challenge for the cryogenic cooling system. The steady-state heat loads are mainly composed of the thermal conduction from the support structure and ...

The stability margin on EAST tokamak
Chinese Physics B, 2009The experimental advanced superconducting tokamak (EAST) is the first full superconducting tokamak with a D-shaped cross-sectional plasma presently in operation. Its poloidal coils are relatively far from the plasma due to the necessary thermal isolation from the superconducting magnets, which leads to relatively weaker coupling between plasma and ...

Equilibrium Reconstruction in EAST Tokamak
Plasma Science and Technology, 2009Reconstruction of experimental axisymmetric equilibria is an important part of tokamak data analysis. Fourier expansion is applied to reconstruct the vessel current distribution in EFIT code. Benchmarking and testing calculations are performed to evaluate and validate this algorithm.

Application of MDSplus on EAST Tokamak
Plasma Science and Technology, 2007EAST is a fully superconducting Tokamak in China used for controlled fusion research. MDSplus, a special software package for fusion research, has been used successfully as a central repository for analysed data and PCS (Plasma Control System) data since the debugging experiment in the spring of 2006 [1]. In this paper, the reasons for choosing MDSplus

The Procedure for Assembling the EAST Tokamak
Plasma Science and Technology, 2005Due to the complicated constitution and high precision requirements of the EAST superconducting tokamak, a meticulous assembling procedure and measurement scheme must be established. The big size and mass of the EAST machine's components and complicated configuration with tight installation tolerances call for a highly careful assembling procedure. The

Runaway Electron Measurements in the EAST Tokamak
Contributions to Plasma Physics, 2010AbstractAn experimental study of runaway electrons in the EAST tokamak has been performed by a recently developed multi‐channel hard x‐ray diagnostics based on NaI(TL) scintillator detectors. It is found that in the current quench phase, the inductive loop voltage plays an important role in the generation of runaway electrons.
