Adhesion analysis of epoxy resin impregnation systems for Nb$_{3}$Sn superconducting magnets
/ Verma, Bharti (CERN) ; Piccin, Roland (CERN) ; Tommasini, Davide (CERN) ; Santillana, Ignacio Avilles (CERN)
The mechanical properties of Nb$_{3}$Sn coils are strongly influenced by the adhesion between the impregnation resin and the coil constituents, which may impact the magnets’ performance. To improve the understanding of the parameters governing the adhesion in such superconducting magnets, a study was conducted on several impregnation systems with respect to different coil parts, notably copper, stainless steel, aluminium, and glass fibre.

Lessons learnt from manufacturing—Forging of tokamak components
/ Sgobba, Stefano (CERN) ; Santillana, Ignacio Aviles (CERN) ; Ruiz-Palenzuela, Berta (CERN ; Carlos III U., Madrid) ; Castro, Enrique Rodriguez (CERN ; Carlos III U., Madrid) ; Knaster, Juan (Euratom, St. Paul Lez Durance) ; Schild, Thierry (Euratom, St. Paul Lez Durance) ; Han, Shiqiang (Euratom, St. Paul Lez Durance) ; Rossano, Graham (Oak Ridge, U.S. ITER) ; Libeyre, Paul (Euratom, St. Paul Lez Durance) ; Beemsterboer, Cornelis (Euratom, St. Paul Lez Durance)
Large structural forgings play a crucial role in the construction of fusion reactors and their superconducting magnet structures. The material challenges of such forged components are addressed, requiring a wide application of tightly specified stainless steel and Nickel-base superalloy products and grades, featuring a controlled microstructure and adequate mechanical, physical, magnetic and vacuum properties over a wide temperature range.
