C-Mod Edge Turbulence at 400,000 frames/sec

taken in collaboration with Jim Terry of MIT

photo of turbulence photo of turbulence These are images of a 6x6 cm region just above the outer midplane of C-Mod. The dashed line is the separatrix and the dotted line is the limiter shadow. These videos were taken at 400,000 frames/sec using a Phantom 710 camera. At the left is a frame of raw 'unormalized data', and at the right is a frame of 'normalized data' made by normalizing all frames to the average frame.
