DOI: 10.1088/1741-4326/ac36f2
Abstract: Enhanced particle transport events are discovered and analyzed as the density limit of the J-TEXT tokamak is approached. Edge shear layer collapse is observed and the ratio of Reynolds power to turbulence production decreases. Simultaneously,… read more here.
