Direct microstability optimization of stellarator devices. [PDF]
Physical Review E, 2023 Turbulent transport is regarded as one of the key issues in magnetic confinement nuclear fusion, both for tokamaks and stellarators. In this work, we show that a significant decrease in a microstability-based proxy, as opposed to a geometric one, for the
