A Tokamak-Stellarator hybrid configuration has been established on the J-TEXT tokamak by the application of stellarator-like External Rotational Transform (ERT) coils. The hybrid configuration aims to combine the advantages of both tokamak and stellarator, particularly to enhance plasma magnetohydrodynamic stability via magnetic configuration optimization, while avoiding the adverse effects commonly associated with resonant magnetic perturbation penetration. Experimental results demonstrate that the hybrid configuration enables complete suppression of both classical and neoclassical tearing modes (TM) and significantly broadens the operational region, increasing the maximum stable plasma current by approximately 20%. During the TM suppression process, a hysteresis-like, nonlinear relationship between the ERT current and the TM amplitude is observed. These findings demonstrate the effectiveness of the hybrid configuration in improving plasma stability and provide a potential pathway for stable operation in future magnetic confinement fusion devices.
