Comprehensive simulations of bursting and non-bursting shear Alfvén waves in ICRF heated tokamak plasmas

Nuclear Fusion
This work reports the first comprehensive simulations of ion cyclotron resonance heating (ICRH) driven tokamak plasmas on the slowing-down timescale using the kinetic-MHD hybrid code MEGA, where shear Alfvén wave induced minority ion transport is self ...

β-induced Alfvén eigenmodes and fishbone driven by energetic electrons in EAST electron heating dominant plasmas

Nuclear Fusion
β-induced Alfvén eigenmodes (e-BAE) and fishbone (e-fishbone) driven by the energetic electrons have been identified on the experimental advanced superconducting tokamak in electron cyclotron resonance heating (ECRH), low hybrid wave (LHW) together with ...

Application of non-axisymmetric magnetic field for control of Alfvén eigenmodes in KSTAR

Nuclear Fusion
We report an experimental examination of non-axisymmetric (3D) magnetic fields for the control of Alfvén eigenmodes (AEs) in KSTAR. Application of the phase-sweeping n  = 1 3D magnetic field identifies the effective 3D field phase and threshold amplitude
