On May 26th 2025, the Divertor Tokamak Test (DTT) project celebrated the completion of its first superconducting toroidal magnet. The milestone was marked at ASG Superconductors’ facility in La Spezia, Italy, in the presence of Minister Gilberto Pichetto Fratin.
DTT is a major Italian fusion initiative promoted by ENEA and supported by EUROfusion. With 18 magnets planned, the project serves as a critical bridge between ITER and DEMO. It will address key challenges in power exhaust management – a central issue on the path to fusion energy.
The 6-meter tall, 16-tonne magnet is the technological core of the DTT machine, capable of containing 33 cubic meters of plasma at temperatures over 100 million degrees Celsius. Its design and manufacture combine industrial innovation and advanced research from across Europe.
EUROfusion Programme Manager Gianfranco Federici commented:
“The successful completion of the first toroidal magnet for DTT is an important technological achievement. DTT is a unique facility that will help us understand and qualify exhaust solutions for DEMO, and EUROfusion is proud to support this project as an important element of Europe’s integrated fusion roadmap.”

DTT represents a successful model of collaboration between public research institutions and private industry. ENEA coordinates the national programme within EUROfusion, aligning efforts from 22 Italian partners.
