Description
Accurate measurement of high-order multipoles in insertion devices is crucial for meeting the beam-dynamics requirements of Swiss Light Source 2.0. A beam-based method using transverse tune-shift measurements can effectively identify sextupole, octupole, and higher-order magnetic components under normal operating conditions, avoiding the need for dedicated magnetic tests. Among the upgraded insertion devices—planar, in-vacuum, and knot-type—only the knot-type device shows significant multipole components beyond sextupole, reaching octupole order. This study focuses on the knot-type device, which is expected to be used in SLS 2.0 and in other modern synchrotron facilities, presenting measurements and comparisons with simulation results.
