In this article, the magnetic measurement data of several production quadrupole and sextupole magnets for the storage ring of the Advanced Photon Source was summarized. But the results were limited to a few parts in 10{sup {minus}4} for storage ring.Abstract:
From the magnetic measurement data of several production quadrupole and sextupole magnets for the storage ring of the Advanced Photon Source, the excitation efficiencies and systematic and random multipole coefficients of the magnets are summarized. The designs of the magnets, which are constrained due to the geometry of the vacuum chamber have rotation symmetries of 180{degrees} and 120{degrees}. The production data meet the allowed tolerances of a few parts in 10{sup {minus}4} for the storage ring.read more
