DOI: 10.1017/s0022377819000217
Abstract: Kinetic treatments of drift tearing modes that match an inner, resonant layer solution to an external magnetohydrodynamic (MHD) solution, characterised by $\unicode[STIX]{x1D6E5}^{\prime }$ , can fail to match the ideal MHD boundary condition on the… read more here.

DOI: 10.1063/1.5006851
Abstract: The effect of helical driven current on the m = 2/n = 1 tearing mode is studied numerically in a cylindrical geometry using the method of reduced magneto-hydro-dynamic simulation. The results show that the local persistent helical current drive… read more here.

DOI: 10.1063/1.5058733
Abstract: The effects of deeply trapped energetic ions (DTEIs) on the stability of tearing modes through stability criterion Δ ′ are studied. In contrast to the stabilizing adiabatic effect of background plasma pressure, the adiabatic contribution… read more here.

DOI: 10.1088/1741-4326/ac1dc4
Abstract: Annular/central collapses of electron temperature have been investigated in the EAST tokamak. The precursor modes are excited before the annular/central collapse events, and the coexistence of multi magnetic island chains can be observed synchronously for… read more here.

DOI: 10.1109/tmag.2021.3053637
Abstract: In this work, a surface current plasma model is coupled to a volume integral formulation for studying the interaction between tokamak tearing modes (TMs) and the machine metallic structures surrounding the plasma. By evaluating the… read more here.
