a The normalized inverse Te gradient scale length and the root-mean-square (RMS) amplitude of the low-k Te turbulence, and (b) the laboratory phase velocity (vL) measurements at two radial positions (red and orange squares) in the inner region near the X-point. The error bar of the RMS amplitude represents the standard deviation of the measurements using different diagnostics channels. The error bar of vL represents the standard deviation of the measurements using different wavenumbers in the broadband spectrum.
