Analysis of synchrotron radiation emitted by runaway electrons in TOKAMAKS

East European Journal of Physics, 2013
The synchrotron radiation diagnostics allows a direct observation of the runaway electron beams and an analysis of their parameters. Strong oscillations of the instantaneous curvature radii of electron orbits were a characteristic feature of recent EAST ...

The Superconducting Magnets for EAST Tokamak

IEEE Transactions on Applied Superconductivity, 2010
The EAST is an Experimental Advanced Superconducting Tokamak. The mission of the EAST Project is to bring out scientific issues on the continuous nonburning plasma scenario of steady-state operation and engineering issues on establishing the basis of technology for superconducting tokamak. Superconducting magnets were chosen for all poloidal field (PF)

A RL-based Vertical Stabilization System for the EAST tokamak

2022 American Control Conference (ACC), 2022
The Vertical Stabilization (VS) is one of the most challenging control problems in tokamak fusion reactors. Existing solutions are usually tailored for the specific device. In this work, a model-free agent trained with the Q-learning algorithm is proposed as a possible alternative solution to the VS problem.

Thermal analysis of the EAST tokamak

Fusion Engineering and Design, 2021
Abstract 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 ...

On plasma vertical stabilization at EAST tokamak

2017 IEEE Conference on Control Technology and Applications (CCTA), 2017
In this paper we discuss the problem of plasma vertical stabilization at the EAST tokamak. By exploiting a plasma/circuit linearized model, we show that the plant cannot be strongly stabilized by using the in-vessel coils and a singleinput-single-output controller that feeds back only the plasma vertical speed z p (i.e. without integral action on z p )

The stability margin on EAST tokamak

Chinese Physics B, 2009
The 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, 2009
Reconstruction 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.
