Enhanced physical understanding of the nature of the Edge Localized Mode (ELM) instability in the H-mode regime of toroidal plasmas requires advanced diagnostic tools to visualize their dynamics. A high spatial and temporal resolution 2-D Electron Cyclotron Emission Imaging (ECEI) system [1] was utilized successfully characterize the real time dynamics of ELMs [2] including the growth, saturation and bursting process of this instability during two campaigns (2010 and 2011) of the Korean Superconducting Tokamak Advanced Research (KSTAR) device. The measured ELMs are validated with the synthetic images based on numerical simulations.
