Topics Plasma impurities, Plasma transport properties, Plasma turbulence, Tokamaks, Magnetic confinement fusion, Turbulent flows The physics of edge plasma in magnetic fusion devices is multifaceted and complex (e.g., see Ref. 1 and the references therein). Even though it has already been studied for a long time, there are still many open issues, including anomalous edge plasma transport, which plays a key role in edge plasma physics.

Atmospheric pressure plasma jet (APPJ) can spray abundant electrons, ions, radicals, and other species into ambient air or onto targeted surfaces.1,2 This process can be adopted close to room temperature, triggering multiple applications in surface modification,3,4 thin-film deposition,5,6 cancer treatment,7,8 wound healing,9 etc. To enlarge the plasma–surface interface for efficient large-scale treatment, researchers grouped multiple jets in close proximity into one jet array.
