Results from the MST reversed field pinch with the design poloidal field windings

Summary form only given. The focus of experimental investigations in the MST reversed field pinch (RFP) is fluctuations, transport, and confinement in a large RFP (R=1.5 m). Initial operation of MST, using the core bias windings as the ohmic heating windings as well, provided observations of magnetic and electrostatic fluctuations in the plasma edge, as well as sawteeth phenomena in the magnetic field and plasma energy. The observed magnetic and electrostatic fluctuation levels warrant further investigation into their relationship to transport. The more distinct sawteeth activity, which could be interpreted as dynamo activity, occurs at all values of the pinch parameter, somewhat in contrast to other RFPs. The temporary poloidal field winding configuration also generated relatively large radial magnetic fields at the poloidal gap
