Scoping the characteristics and benefits of a connected double-null configuration for power exhaust in EU-DEMO

A double-null configuration is being considered for the EU-DEMO, due to its potential benefits power exhaust arising from use of two active divertors and magnetically disconnected low- high-field sides. Using systematic parameter scans in fluid simulations, we have investigated divertor EU-DEMO a connected configuration, compared edge plasma properties those obtained single-null under detached conditions anticipated reactor operation. Neglecting drift effects kinetic behaviour neutrals, no clear could yet be identified radiation pattern mitigation on open field lines. Future work should address aforementioned physics as well effect additional X-point core radiation.
