\textbf{ELM Suppression by Boron Powder Injection: Analysis of Edge Turbulence}*

Type I edge-localized modes (ELMs) in EAST were completely suppressed via boron powder injection into the X-point region of an upper-single null configuration over a wide range of operating conditions (2.8 \textless P$_{\mathrm{aux}}$ \textless 7.1 MW, 3.8e19 \textless n$_{\mathrm{e\thinspace }}$\textless 6e19 m$^{\mathrm{-3}}$, RF-only and RF$+$NBI heating scenarios). There appears to be a window of edge B concentration for stable long pulse operation. The injection of Boron coincides with the onset on many modes on the magnetic spectrograms showing multiple dependences with line-averaged densities. In this work, we will present analysis of mode localization using the radial density profile measured with O-mode sweeping reflectometry. Finally, initial analysis of power balance will be discussed.
