Back in 1992-1993, AET worked with Columbia University’s Plasma Physics Lab on a Tokamak fabrication. This first-of-its-kind Tokamak has movable walls throughout to get fine adjustment of the test plasma.
As stated on the Columbia Plasma Physics Lab Website here, https://bit.ly/3ydnjuD
“HBT-EP is a unique experiment for the investigation of wall-stabilization being the only tokamak device built with adjustable walls and having a vacuum chamber made with several quartz cylindrical breaks. These breaks allow fast penetration of externally-applied magnetic perturbations. HBT-EP has accelerated magnetic islands of nearly sonic speed and the device has been used to access the Troyon normalized beta limit with ohmic heating alone.”
