    Abstract:

    Bernstein-extraordinary-ordinary mode-converted electron Bernstein wave (EBW) emission was angularly scanned at the Mega Ampere Spherical Tokamak (MAST). Radiometry along a rapidly steering line of sight sampled the conversion efficiency contours for various view angles. Here we describe the diagnostic, present the first results and illustrate their potential as an indirect measure of the q profile at the plasma edge.
