Erratum: New Steady-State Quiescent High-Confinement Plasma in an Experimental Advanced Superconducting Tokamak [Phys. Rev. Lett. 114, 055001 (2015)].

In our recently published work, there is an error in the stated direction of the edge coherent MHDmode (ECM) associated with real-time Li injection. This error does not affect the main results of the paper. The direction of the ECMwas obtained from two high sampling-frequencyMirnov magnetic pickup probes. In the Letter, we reported that the ECM propagates in the ion diamagnetic drift direction. The ECM actually propagates in the electron diamagnetic drift direction, consistent with the identified direction in our previous study [1].
