Alcator C-Mod Edge Turbulence
photo of turbulence Images of edge turbulence taken with the Princeton Scientific Instruments PSI-3 camera at 4 microsec/frame and 250,000 frames/sec. The movement of two locally bright "blobs" is tracked over several frames showing their velocity of up to 1 cm / 20 microsec.

In the pictures at the left, the radially outward direction is to the left and the ion grad-B and ion diamagnetic direction is downward.
