Abstract
One of the main challenges in the European fusion roadmap is to design a heat and power exhaust system able to withstand the large loads expected in the divertor of a DEMO fusion power plant. Therefore, in parallel with the programme to optimise the operation with a conventional divertor based on detached conditions to be tested on the ITER device currently under construction in Cadarache, a specific project has been launched to investigate alternative power exhaust solutions for DEMO, aimed at the definition and the design of a Divertor Tokamak Test facility. This tokamak should be capable of hosting scaled experiments integrating most of the possible aspects of the DEMO power and particle exhaust. DTT should retain the possibility to test different divertor magnetic configurations, liquid metal divertor targets, and other possible solutions for the power exhaust problem. The DTT design proposal refers to a set of parameters selected so as to have edge conditions as close as possible to DEMO (in terms of the temperature and the normalized collisionality, pressure and ion gyro radius), while remaining compatible with DEMO bulk plasma performance in terms of dimensionless parameters within a set of constraints related to flexibility and costs.
