The first period of physics operation of the Madison Symmetric Torus (MST) reversed field pinch (Proc. 12th Intl. Conf. on Plasma Physics and Cont. Fusion, I.A.E.A., 1988) has produced information on sawtooth oscillations, edge magnetic and electrostatic fluctuations, and equilibrium parameters at large plasma size. Sawtooth oscillations are prevalent at all values of pinch parameter, and might constitute discrete dynamo events. Both electrostatic and magnetic fluctuations are of sufficient magnitude to be relevant to transport in the RFP. In the plasmas studied to date (up to a plasma current of 0.5 MA) the poloidal beta value is about 10%, or greater.
