Abstract :
Detailed studies of the SNS ring lattice optics have been conducted. The horizontal and vertical tuning ranges for matched solutions with well-behaved lattice functions were determined and the power supply margin verified. Using stability criteria, potential working points have been identified and studied in detail. Studies, focused on behavior of the lattice functions under increasingly complex assumptions, included chromatic effects and sextupoles, and lattice perturbations due to the injection chicane and to dynamic bumps for painting. Results are being used in determining injection painting schemes, in dynamic aperture studies, and in validating collimator settings
