Key Takeaway

Key Takeaway: The 7-GeV Advanced Photon Source CDR lattice's stability region is limited by chromaticity correcting sextupoles and the predominance of the integral resonance for vsub x = 0.88 per period.

Abstract

A comparison between the predicted stability region and the results of tracking for the 7-GeV Advanced Photon Source CDR lattice is given. The tracking results are obtained by searching for the limit of stability in N{sub y} for a fixed value for N{sub x}. (Negative N{sub x} is understood to mean cos {phi}{sub xo} = {minus}1.) The limits of the stable region for this lattice are caused by the chromaticity correcting sextupoles and the predominance of the integral resonance for v{sub x} = 0.88 per period.
