  title = {Phase-locking of magnetic islands diagnosed by ECE-imaging},
  abstract = {Millimeter-wave imaging diagnostics identify phase-locking and the satisfaction of 3-wave coupling selection criteria among multiple magnetic island chains by providing a localized, internal measurement of the 2D power spectral density, S(ω, k pol ). In high-confinement tokamak discharges, these interactions impact both plasma rotation and tearing stability. Nonlinear coupling among neoclassical tearing modes of different n-number, with islands not satisfying the poloidal mode number selection criterion ⟨m, m ′, m − m ′⟩, contributes to a reduction in core rotation and flow shear in the vicinity of the modes. },
