Superconductors for fusion: a roadmap
/ Mitchell, Neil (Euratom, St. Paul Lez Durance) ; Zheng, Jinxing (Hefei, Inst. Plasma Phys.) ; Vorpahl, Christian (EFDA-CSU, Garching) ; Corato, Valentina (ENEA, Frascati) ; Sanabria, Charlie (Unlisted, US) ; Segal, Michael (Unlisted, US) ; Sorbom, Brandon (Unlisted, US) ; Slade, Robert (Unlisted, GB) ; Brittles, Greg (Unlisted, GB) ; Bateman, Rod (Unlisted, GB) et al.
With the first tokamak designed for full nuclear operation now well into final assembly (ITER), and a major new research tokamak starting commissioning (JT60SA), nuclear fusion is becoming a mainstream potential energy source for the future. A critical part of the viability of magnetic confinement for fusion is superconductor technology. [...]

Progress on the Upgrade of EDIPO, a 15 T Large Aperture Dipole
/ Araujo, Douglas Martins (CERN) ; Ballarino, Amalia (CERN) ; Bordini, Bernardo (CERN) ; Bottura, Luca (CERN) ; Hopkins, Simon C (CERN) ; Perez, Juan C (CERN) ; Ravaioli, Emmanuele (CERN) ; de Rijk, Gijs (CERN) ; Bruzzone, Pierluigi (Ecole Polytechnique, Lausanne) ; Sarasola, Xabier (Ecole Polytechnique, Lausanne) et al.
The upgraded magnet assembly of the EDIPO test facility aims at generating 15 T at 4.2 K and 85% of short sample limit in a large rectangular aperture and over a uniform field length of 1000 mm. During 2020 the design studies have concentrated on two flared-end block-coil design options with four double-pancake coils, two per pole. [...]

Plasma Phys.) et al.
The Comprehensive Research Facility for Fusion Technology (CRAFT) project has been launched in 2019, for developing the essential engineering technologies for Chinese Fusion Engineering Testing Reactor (CFETR). Within this project, a full-size toroidal field (TF) coil will be built as the prototype coil for CFETR. [...]

The 16 T dipole development program for FCC and HE-LHC
/ Schoerling, Daniel (CERN) ; Arbelaez, Diego (LBNL, Berkeley) ; Auchmann, Bernhard (PSI, Villigen) ; Bajko, Marta (CERN) ; Ballarino, Amalia (CERN) ; Barzi, Emanuela (Fermilab) ; Bellomo, Giovanni (INFN, Milan) ; Benedikt, Michael (CERN) ; Izquierdo Bermudez, Susana (CERN) ; Bordini, Bernardo (CERN) et al.
A future circular collider (FCC) with a center-of-mass energy of 100 TeV and a circumference of around 100 km, or an energy upgrade of the LHC (HE-LHC) to 27 TeV require bending magnets providing 16 T in a 50-mm aperture. Several development programs for these magnets, based on Nb$_3$Sn technology, are being pursued in Europe and in the U.S. [...]

A large aperture Nb$_3$Sn dipole is proposed to replace the magnet assembly of EDIPO, which was irreversibly damaged in 2016. The goal is to generate a background field of 15 T at 4.2 K in a clear aperture of approximately 100×150 mm$^2$ and over a uniform length of 1000 mm in order to test superconducting cables for both fusion and high-energy physics applications.
