Abstract

We have studied the methods for the determination of reference closed orbit of the storage ring in PLS using magnet misalignment data. The reference closed orbit was determined by (1) a smoothing analysis using a low-pass filter method, and (2) a MAD (methodical accelerator design) simulation using the real parameters such as magnet misalignment data. Based on the estimated reference closed orbit, the relative positional errors of the storage ring magnets were evaluated. The results of case studies on the comparison of the smoothing analysis and the MAD simulation are described in this presentation
