PFC / JA-95-12 A Comparison of Soft X-Ray Emissivity Contours with Magnetic Flux Surfaces in Alcator C-Mod


The soft X-ray diagnostic system of Alcator C-Mod, equipped with 152 detectors distributed in 4 arrays, has been used to obtain iso-emissivity surfaces. We characterize these surfaces by giving their elongation and relative shift from the center of the tokamak as functions of plasma radius. Flux surfaces, provided by magnetic diagnostics, have also been… (More)
