11:00 → 12:00 Fusillo: Design, Fabrication and Test of a Curved-Canted-Cosine-Theta (CCCT) Dipole

Canted Cosine Theta (CCT) magnet is a very interesting design for compact accelerators or gantry systems for hadron-therapy. Indeed, it offers great flexibility in generating complex field harmonics in straight and curved configurations for which compactness is even higher. The Fusillo project at CERN aims to design, build, and test a Nb-Ti curved CCT dipole demonstrator generating 3 T at 4.5 K in a large aperture of 236 mm, bent over 90° with a small bending radius of 1 m, and multi-harmonic field features to correct for the curvature. In this presentation, we describe the design, the fabrication process, the winding and the assembly of a Fusillo demonstrator. We report on the test results in liquid helium, including quench performance, and magnetic field measurements.
