During the last years growing interest in stellarators as toroidal magnetic confinement devices becomes evident. In spite of many restrictions, e.g., small minor radius a ˜0.1 m, plasma parameters comparable to those in tokamaks have been achieved.

The stellarator is a plasma confinement system in which the magnetic field configuration is produced by currents in conductors outside the plasma. Plasma current is not necessarily required for confinement or for heating the plasma. Results from the

This report collects together results on the containment of plasma injected into the PROTO-CLEO stellarator, some of which have been previously presented as conference papers. The importance of fluctuations on plasma containment is also discussed and

Tokamak and Ohmically heated stellarator plasmas have been compared in the CLEO apparatus, using gas current in the range 10--25 kA at a toroidal field of 12.7 kG. It is found that the vacuum poloidal field due to the helical winding has a considerab

Regular oscillations have been detected under a limited range of conditions in a 12-in. bore torus. The electric and magnetic fields associated with these have been investigated and indicate a helical notch of reduced density travelling on the pinche

The diffusion of the current sheath in ZETA is shown to be incompatible with classical resistive diffusion at high rates of energy input or low pressures. In the anomalous region the diffusion time is approximately proportional to mass density and in
