Abstract

A description is given of the design and initial operation of a small (outer radius/inner radius=50 cm/8 cm) reversed field pinch air core, a thin removable shell, and relatively low field errors. Equilibrium control is simplified by having no vertical field generated by the ohmic heating coils so that the equilibrium is determined solely by the variable index preprogrammed vertical field coil current. The toroidal field and vertical field coils are inductively decoupled from the ohmic heating circuit in order to simplify the programming of these fields. Discharges having a 22 kA plasma current and duration of 500 mu sec are obtained.<>
