This paper summarizes the evidence for the role of shear flow in confinement improvement during electrode biasing experiments in TEXTOR-94: the transport barrier spatially overlaps the shear layer, the temporal causality is clearly established and the magnitude of shear at which the confinement occurs, agrees rather well with theoretical models. These results strengthen the conjecture that stabilization is a viable mechanism for improved confinement in tokamaks.
