The Torsatron/Stellarator Laboratory Program during the present period has concentrated on experimental investigations into ECR-produced plasmas in the IMS device. Significant progress has been made in understanding the role of convection in maintaining the hollow plasma density profiles under a wide range of operating conditions. Divertor studies have continued to show good agreement with predictions derived from simple field-line models and the ability to effect particle flows through biasing of divertor plates. Preliminary fluctuation studies showed a dependence of the amplitudes of the fluctuations and profile shapes as a function of the magnetic topology of the device. Theoretical support of the experimental program has provided models to help interpret the experimental results. New initiatives have begun in reduced-Q operation of the Proto-Cleo Stellarator, and in ion-Bernstein wave heating in IMS.
