Description
The Divertor Tokamak Test facility (DTT) [1] is a research infrastructure proposed first in the EFDA Roadmap [2] to investigate innovative solutions for the heat exhaust in the DEMOnstration fusion power plant.
DTT is a compact experiment (major radius R=2.2m, minor radius 0.7m) that mimic the heat generated by fusion reactions using a large amount of external heating power (up to 45MW at the plasma). The DTT plasma current of 5.5MA allows to achieve breakeven-class plasma conditions. The DTT magnet system (toroidal filed B=5.7T) will be made of superconducting components to allow long pulse operation (pulse length of the order of 100s). This, in turn requires all the in-vessel components be actively cooled.
DTT is presently under construction at the ENEA Frascati laboratory by a consortium (DTT s.c.ar.l.) that involves all the Italian public institutions working in fusion and the largest Italian energy company. The presentation will give a description of the scientific program and of the status of the construction.
