Abstract: Dynamic mitigation for the tearing mode instability in the current sheet in collisionless plasmas is demonstrated by applying a wobbling electron current beam. The initial small amplitude modulations imposed on the current sheet induce the… read more here.

DOI: 10.1088/1741-4326/aa823c
Abstract: Periodic destabilization of a neoclassical tearing mode (NTM, m/n = 2/1) in between two edge localized modes (ELMs) is observed with a varying frequency that deviates from the wave-particle resonance determined precession frequency, is instead… read more here.

DOI: 10.1088/1741-4326/ab8180
Abstract: Turbulent fluctuations within a quasi-coherent frequency range (peak frequency of ~ 130 kHz, ∆f ≈ tens of kHz) are modulated by the rotation of low frequency tearing modes in the core of HL-2A ohmic plasmas.… read more here.
