摘要：

The Canted-Cosine-Theta (CCT) magnet design offers significant reductions in conductor stress by using mandrels to prevent the accumulation of operating Lorentz forces. Each mandrel consists of a cylindrical spar with ribs guiding the conductor. These ribs intercept the turn-to-turn accumulation of forces by transferring them to the spar. Design studies of a layered CCT coil pack coupled to a shell-based structure are shown. The use of a 3-D periodic symmetry region to reduce the problem size for finite element modeling is detailed along with a discussion of axial boundary conditions. ANSYS calculation results for a two layer NbTi dipole being constructed at LBNL (CCT1) are presented. ANSYS calculations show the Lorentz force induced stress in CCT1 at the single turn level, demonstrating interception and suggesting investigation of CCT design with minimal structure external to the coil pack.
