DOI: 10.1088/0029-5515/57/2/022018
Abstract: H-mode is obtained at $$A\sim 1.2$$ in the Pegasus Toroidal Experiment via Ohmic heating, high-field-side fueling, and low edge recycling in both limited and diverted magnetic topologies. These H-mode plasmas show the formation of edge… read more here.

DOI: 10.1103/physrevlett.129.205001
Abstract: Experiments on the DIII-D tokamak have identified a novel regime in which applied resonant magnetic perturbations (RMPs) increase the particle confinement and overall performance. This Letter details a robust range of counter-current rotation over which… read more here.
