Abstract
In this article, we attempt to summarize the 5-year long involvement of PSI through the CHART MagDev program with R&D on the Canted Cosine Theta (CCT) technology as a candidate for an FCC-hh main dipole magnet. We present the test results of the Canted Dipole 1 (CD1) 1-m-long 10-T Nb <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$_{3}$</tex-math></inline-formula> Sn demonstrator magnet, as well as a subjective list of ’pros and cons' of CCT for the FCC-hh that we compiled along the way. By sharing our conclusions, we hope to contribute to an ongoing discussion, while maintaining our utmost respect to the community of CCT developers. The presented findings and conclusions are not final, and we remain open to arguments and discussions, as well as technical exchanges on the topic.
