The Madison Symmetric Torus (MST) is the newest and largest
pinch (RFP) currently in operation. It incorporates a number of
features that set it apart from other pinches, including the use of
conducting shell as both a vacuum vessel and single-turn toroidal
coil. Specially insulated voltage gaps are exposed to the plasma.
field errors at the gaps as well as at the various diagnostic and
ports are minimized through a variety of techniques. The physics
of MST include study of the effect of large size on confinement and
detailed investigation of RFP turbulence, dynamo, and transport.
of the design and initial operation of the device are presented.
