Study of the penetration of resonant magnetic perturbations in J-TEXT

Nuclear Fusion, 2014
In the J-TEXT tokamak, the penetration of resonant magnetic perturbations (RMPs) has been studied by using a set of in-vessel RMP coils. It is found that, once the RMP amplitude exceeds a critical value, the applied RMP can lead to field penetration and excitation of a large locked mode in the tearing-stable plasma.

The design and application of Alfvén antennas in J-TEXT tokamak

Fusion Engineering and Design, 2018
Abstract Research on Alfven waves and Alfven eigenmodes is of importance in tokamak plasma physics, such as investigation of interaction between energetic particles and AEs, turbulence and anomalous transport due to AEs, and so on. An Alfven antennas system is designed for J-TEXT tokamak in order to study the Alfven eigenmode excitation, damping ...

Progress of recent experimental research on the J-TEXT tokamak

Nuclear Fusion, 2017
The progress of experimental research over the last two years on the J-TEXT tokamak is reviewed and reported in this paper, including: investigations of resonant magnetic perturbations (RMPs) on the J-TEXT operation region show that moderate amplitude of applied RMPs either increases the density limit from less than 0.7n G to 0.85n G (n G is the ...

Rogowski Sensor for Plasma Current Measurement in J-TEXT

IEEE Sensors Journal, 2009
Rogowski coil is very useful in transient current measurement. Rogowski sensor consisting of Rogowski coil and integrator is one of the most important diagnostic instrumentations in Tokamak. In recent years, new structures of Rogowski coil based on printed circuit board (PCB) are developed to replace traditional handmade Rogowski coil for more ...
