Description
We report on the development of an advanced storage ring lattice, the Stanford Diffraction-Limited Light Source (SDLS), tailored for installation in the existing PEP-II tunnel at SLAC. The design is based on the hybrid 6-bend achromat (H6BA) architecture optimized for ultra-low emittance while maintaining robust nonlinear dynamics, essential for diffraction-limited synchrotron radiation production. To accommodate long straight sections required for insertion devices and injection systems, we implement the mmodified transparency conditions that mitigate periodicity-breaking effects and preserve dynamic aperture and momentum acceptance. This latest design advances the SDLS concept by combining a new compact (insertion device-less) cell in half of the arcs and the H6BA in the remaining half of arcs. Nonlinear optimization—via multi-objective algorithms incorporating tune footprint control, frequency map analysis, and chromatic detuning minimization—yields a dynamic aperture sufficient for off-axis injection and a Touschek lifetime exceeding those of contemporary third-generation sources.
