Coil manufacturing process of the first 1-m-long Canted–Cosine–Theta (CCT) model magnet at PSI

At the Paul Scherrer Institute (PSI), the Canted-Cosine-Theta (CCT) magnet program aims at demonstrating that CCT technology is a viable candidate for the development of 16-T dipole magnets, required for future circular colliders. The first step in this direction is the implementation of a Nb$_3$Sn 1-m-long, two-layer CCT single-aperture dipole, referred to as Canted Dipole One (CD1), which is designed to achieve a peak field in the bore of ~11 T. The in-house manufacturing and assembly of CD1 requires the infrastructure for a number of fabrication steps to be set up at PSI. In this paper, the authors review the coil manufacturing process of Nb$_3$Sn CCT model magnets at PSI and describe the related commissioning phase.
