Abstract

Research on Alfvén waves and Alfvén 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 Alfvén antennas system is designed for J-TEXT tokamak in order to study the Alfvén eigenmode excitation, damping features and so on. For a typical J-TEXT plasma, the computed gaps in the Alfvén continua range from 300 to 500 kHz, with respect to the Alfvén waves dispersion relation. Three pairs of antennas are designed at different toroidal angels respectively on the low field side. Each pair consisting of two coils installed with angles of ±45 off the mid-plane along the poloidal direction. With this system, strong magnetic field components of different mode number can be produced.
