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 Nb3Sn 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 Nb3Sn CCT model magnets at PSI and describe the related commissioning phase.
