MST Terrella Experiment



 

Overview:

A terrella (permanent magnet simulating the interaction of plasma with earth's magnetosphere) was inserted into the edge plasma of Madison symmetric torus with a 300-400kA discharge and imaged with an 80k frames/sec camera.

Terrella (8/23/2013)

A terrella was placed in a 300-400kA discharge in Madison Symmetric Torus and imaged at 79k fps. Towards the end of shot, the terrella came loose from it's mounting screw and began to rotate, providing an angular sweep of magnetic field.
