Dynamic aperture studies for SPEAR 3

The SSRL is investigating an accelerator upgrade project to replace the present 130 nm-rad FODO lattice with an 18 nm-rad double bend achromat lattice: SPEAR 3. In this paper, we review the methods used to maximize the SPEAR 3 dynamic aperture including optimization of linear optics, betatron tune, chromaticity and coupling correction, and effects of machine errors and insertion devices.
