A Summary of Containment Experiments on the PROTO-CLEO Stellarator, 1968-1974

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 an attempt made to arrive at momentum balance for the ions and electrons. It is concluded that although plasma can be contained for periods as long as expected on the basis of loss solely by collisions, it cannot be conclusively demonstrated that this is the sole mechanism of plasma loss, since evidence for the existence of the diffusion driven current cannot be found.
