- To satisfy a demand for high energy, high brightness x-ray sources at the Advanced Light Source (ALS), a plan is in place to replace three 1.3 Tesla normal conducting bending magnets with three 5 Tesla superconducting magnets (superbends) in the year 2001. In this paper they discuss the impact of the superbends on the ALS beam parameters and particle dynamics. In particular they show the effect on the emittance, energy spread, and lifetime. They find that by adjusting the dispersion to be positive in the straight section they are able to largely restore the horizontal emittance. The vertical emittance can be adjusted independently to control the lifetime. The particle dynamics are investigated through particle tracking with a frequency analysis postprocessor. They find that by placing the three superbends symmetrically around the ring there is ample dynamic aperture for injection and lifetime.
