Abstract
Collisional transport theory predicts particle depletion in the core of reactor-relevant fusion plasmas confined in stellarators. However, this prediction is contradicted by experiments. The conundrum has been solved by proving that turbulence provides the missing transport component that allows the reconciling of theory and experiment.
