MISE (Ministero dello Sviluppo Economico – Italian Ministry of Economic Development) and MIUR (Ministero dell’Istruzione, Università e Ricerca - Italian Ministry of Education, University and Research), allocate a financial contribution of 80 M€ for the DTT Project

June 2017

The conclusion of EUROfusion DTT Workshop held in Frascati is that the design of a DTT facility should offer sufficient flexibility to be able to incorporate the best candidate divertor concept (e.g. conventional, snowflake, super-X, double null, liquid limiter) even at a later stage of its realization

July 2017

An interim DTT Project Board is nominated and an interim DTT Team is established

Oct 2017

The DTT Team prepares a feasibility study focusing on flexibility, up-down symmetry, and additional power specifications

Oct 2017

On the basis of the feasibility study submitted by the DTT Team, the General Assembly of EUROfusion approves the principle of involvement of EUROfusion in the DTT facility around 2022-23, within a ceiling of 60 M€ for the divertor system

Nov 2017

Fusion Engineering and Design publishes a special issue on DTT

Dec 2017

The activities of Work Package WPDTT2 come to the end, since DTT becomes an Italian project supported by EUROfusion

Mar 2018

Frascati hosts the first national workshop on DTT Physics (“Prima riunione nazionale sulla fisica del DTT”)

Apr 2018

The General Assembly of EUROfusion decides that 60 M€ should be earmarked for DTT in FP9, delaying the decision on the most appropriate involvement of EUROfusion around 2022-2023, when EUROfusion will be able to propose a divertor to be tested or the DTT plant will be at a stage with a low risk to non-completion.
