This paper addresses electromagnetic losses in Canted-Cosine-Theta (CCT) magnets, especially relevant for fast-ramped, conduction-cooled CCTs in hadron therapy.

Abstract

This paper addresses electromagnetic losses in Canted-Cosine-Theta (CCT) magnets, especially relevant for fast-ramped, conduction-cooled CCTs in hadron therapy. It discusses losses in metallic formers, using both analytical models and FEM simulations. It then addresses losses in multifilamentary superconductors under AC fields, accounting for persistent and interfilament losses under longitudinal and transversal field with a 3D Volume Integral Method. As a closing example, losses of the LTS (Nb-Ti) CCT dipole designed in HITRI and I.FAST collaborations are computed.
