Analysis of KEK-ATF Optics and Coupling Using LOCO

DOI:https://doi.org/10.2172/889309· OSTI ID:889309
LOCO is a code for analysis of the linear optics in astorage ring based on the closed orbit response to steering magnets. Theanalysis provides information on focusing errors, BPM gain and rotationerrors,and local coupling. Here, we report the results of an applicationof LOCO to the KEK-ATF. Although the analysis appears to have provideduseful information on the optics of the machine, it appears that one ofthe main aims of the study to reduce the vertical emittance by correctingthe local coupling was not successful, and we discuss some possiblereasons for this.
