Abstract :
Design of quadrupole magnets for a compact ion accumulation and cooler ring, S-LSR, is presented. By requirements from lattice parameters and spatial boundaries for real installation in S-LSR, quadrupole magnets with relatively short magnetic length but wide horizontal aperture are needed. In this paper, we present results obtained from magnetic field calculations by 2D and 3D modelings, and describe the optimization of a pole face shape and fringing edge (chamfer cut design).
