Sawtooth-like oscillations and steady states caused by the m/n=2/1 double tearing mode

Wei Zhang et al.

Summary: The study numerically investigates the sawtooth-like oscillations resulting from the m/n = 2/1 double tearing mode. It finds that the behavior of the oscillations is influenced by the perpendicular thermal conductivity and external heating rate. The steady state with m/n = 2/1 radial flow might be beneficial for future fusion reactors.

Viscous effects on plasmoid formation from nonlinear resistive tearing growth in a Harris sheet

Nisar Ahmad et al.

Summary: The evolution of a highly unstable m = 1 resistive tearing mode, leading to plasmoid formation in a Harris sheet, is studied in this work using the Non-Ideal Magnetohydrodynamics with Rotation, Open Discussion simulation. Two distinctive viscous regimes are found for the plasmoid formation and saturation, with the plasmoid width increasing sharply with viscosity in the low viscosity regime and gradually decreasing with viscosity in the viscosity dominant regime. The role of viscosity in modulating the plasmoid formation process through its effects on the plasma flow and reconnection is quantified.

Linear and nonlinear benchmarks between the CLT code and the M3D-C1 code for the 2/1 resistive tearing mode and the 1/1 resistive kink mode

W. Zhang et al.

Summary: By comparing the simulation results of CLT code and M3D-C1 code, it was found that they were almost identical in terms of resistive kink mode and tearing mode, including linear and nonlinear growth rates. This indicates that the simulation results for the 1/1 resistive-kink mode and 2/1 tearing mode are accurate and reliable.

Nonlinear evolution and secondary island formation of the double tearing mode in a hybrid simulation

Aohua Mao et al.

Summary: In this study, the evolution of DTMs without a guide field is numerically investigated using a hybrid model, showing qualitative consistency with previous works and analyzing particle dynamics in detail. Different behaviors of ions and electrons around the reconnection region lead to Hall effects producing the out-of-plane quadrupole magnetic field, and the explosive reconnection process results in the emergence of secondary magnetic islands due to asymmetric drive and thin current layer features.
