The management of plasma exhaust is one of the most intricate and pressing challenges facing magnetic confinement fusion. Fusion power-plants like STEP may direct more heat to surrounding material than is experienced by spacecraft upon re-entry into earth; and for an economic fusion plant these materials must survive for years of full power operation. Luckily, there are many potential solutions to the exhaust challenge, and one such solution is to cleverly design the divertor, which manages the majority of plasma exhaust. Novel alternative divertor configurations are predicted to have many benefits, particularly for the operational mode known as detachment. In this talk, we will look at these benefits, and how well these predicted benefits are reproduced by high-fidelity simulations and experiments.
