Construction of combined CCT demonstrator

This report presents the as-built details of the combined Canted Cosine Theta (CCT) magnet demonstrator based on LTS developed within Task 8.4 of WP8 – Innovative Superconducting Magnets in the I.FAST project. The demonstrator is a straight, two-layer combined CCT magnet designed to achieve a central dipole field of 4 T at 4.2 K, using a Nb-Ti 6 strands + 1 copper core strand cable configuration and targeting a ramp rate of 0.4 T/s. The document describes the final design configuration, conductor and joint characteristics, and manufacturing and assembly procedures.
