Investigating ELM Pacing by Vertical Oscillations on DIII-D

Edge Localized Modes (ELMs) have been observed to be triggered by fast vertical oscillations of the plasma on multiple tokamak devices. These vertical plasma oscillations have been considered as a possible alternative ELM pacing mechanism for future fusion reactors. This work presents analysis of a DIII-D shot with vertical plasma oscillations. Shot analysis will be shown, in an attempt to determine if ELM pacing was achieved. Stability analysis performed during the course of the oscillations will also be presented.
