Divertor Target Design for the UWTOR-M Modular Stellarator Power Reactor

Modular stellarators offer a unique opportunity for innovative divertor target design by virtue of the discreteness of their diverted flux bundles. Well focused flux bundles leave the separatrix at discrete locations, emerging from the toroid between the coil legs and then re-enter the toroid. This paper describes a divertor target design which recovers the energy at a high temperature and prevents neutron streaming through the divertor slots.
