The development of a reliable solution for the power and particle exhaust in a reactor is recognised as one of the major challenges towards the realisation of a nuclear fusion power plant [https://www.euro-fusion.org/wpcms/wp-content/uploads/2013/01/JG12.356-web.pdf]. In order to mitigate the risk that the conventional divertor solution that will be tested in ITER may not extrapolate to DEMO, alternatives must be developed. While several alternatives, such as the cooled liquid Li limiter in FTU, the Super-X divertor in MAST-U or the Snowflake divertor in TCV are being investigated in present devices, the extrapolation to DEMO is considered to large [https://www.euro-fusion.org/wpcms/wp-content/uploads/2013/01/JG12.356-web.pdf]. The role of the DTT facility is to bridge the gap between today's proof-of-principle experiments and DEMO. DTT should, in particular, have the potential to bring such solutions to a sufficient maturity level that they could be adopted on DEMO.
