Summary: This study presents the first demonstration of high current Bi-2212 coils using CCT technology, showing that they can achieve high peak currents and exhibit no quench training. The results suggest that CCT technology is a promising route to develop high-field, potentially quench training-free dipole magnets with Bi-2212 cables.

Summary: This paper presents the results of FEM analysis on the impact of REBCO CORC cable magnetization on the field quality of a CCT dipole magnet. The magnetic properties of the CORC cable were determined through measurements of its M(H) curves at 4.2 K and magnetic fields up to 8 T. The calculated field errors based on the magnetization data were compared with experimental results, showing reasonable agreement.

Summary: The Canted Cosine Theta layout for accelerator magnets is being developed for cancer therapy. The magnets are designed to be manufactured easily and with fewer parts. Different coil materials are compared, and low current operation is preferred to minimize heat generation. Two magnet demonstrators, including a straight combined function dipole-quadrupole and a curved CCT dipole, are designed based on the comparison results.
