Description
Oral presentation (25 min) + Q&A (10 min)
The EDIPO 2 test facility will complement and enhance SULTAN at EPFL-SPC, which has qualified superconductors for all major superconducting fusion facilities worldwide over the past two decades. EDIPO2 will significantly enhance the high-current and high-field testing capabilities at EPFL-SPC to align with the requirements of the new generation of superconducting samples, driven by the development of High Temperature Superconductors. The background field of EDIPO 2 will reach 15 T (compared to 10.9 T in SULTAN) in the center of a square aperture of 144×144 mm2 (94×144 mm2 in SULTAN) and its superconducting transformer is designed for testing samples beyond 100 kA. In recent years, EPFL-SPC has developed the conceptual design for the EDIPO2 magnet which relies only on planar racetrack coils wound with a flat two-stage cable. This presentation will provide an overview of the EDIPO 2 design and the latest progress, including the procurement of the Nb3Sn strand, the production of prototype copper dummy and Nb3Sn cables, and the initiation of technological R&D and engineering design for coil manufacturing.
