The Divertor Tokamak Test Facility (DTT) is a new tokamak whose construction has recently been approved by the Italian government. DTT will be a high field superconducting toroidal device (6 T) carrying plasma current up to 5.5 MA in pulses with length up to 100s and with 45 MW of additional heating power, with an up-down symmetrical D-shape defined by major radius R=2.11 m, minor radius a=0.64m.

DTT key mission is contributing to the development of a reliable solution for the power and particle exhaust in a magnetic confinement fusion reactor, a challenge commonly recognised as one of the major issues in the roadmap towards a fusion power plant. In addition to its main goal, DTT will be a flexible high-performance device – equipped with advanced control tools - aiming at the investigation of fully integrated core-edge scenarios, both in standard and advanced tokamak configurations.

This talk will briefly discuss the path which lead to the DTT approval, give an overview of the DTT interim design and illustrate the present main physics and technical choices, the overall status of the project and the plan for the short and medium-term future.
