Description
We report the status of the high-brightness, low-beta optics for the Diamond-II storage ring upgrade. Investigations into the dependence of lifetime and injection efficiency on betatron tunes will be presented. MOGA optimisation studies have been conducted to improve the nonlinear performance, including by increasing the number of sextupole families and varying the octupoles strengths. We present complementary methods to improve the nonlinear dynamics by optimizing second and third order tune-shifts as well as the nonlinear chromaticity. Finally, we report the impact of insertion devices on lifetime and dynamic aperture and present studies of the injection process.
