Title: Beam-Optics Analysis and Periodicity Restoration in the Storage Ring of the Pohang Light Source

Abstract

In this paper, we examine numerically and experimentally the linear beam optics distortion in the storage ring of the Pohang Light Source (PLS), and the correction of optics using a number of quadrupole magnets installed in the storage ring. The measured orbit-response matrices were fitted to the model-response matrices to obtain {beta} and dispersion functions in storage ring. By readjusting currents of quadrupole-magnet power supplies, optics parameters were successfully restored to the values very close to the design ones. After the optics correction, it is expected that the performance of the storage ring is better than the present one.
