MAGNETIC MEASUREMENTS RESULTS OF THE DIPOLES, QUADRUPOLES AND SEXTUPOLES OF THE SOLEIL STORAGE RING

During the magnetic measurement campaign, from May 2004 to August 2005, the 326 electro-magnets of the SOLEIL Storage Ring (SR) [1] have been characterized in terms of magnetic axis centering and field properties. For the dipoles, field mapping and field integral comparison with a reference dipole have been performed. For the quadrupoles, a rotating coil bench has been built and optimized at SOLEIL in order to reach magnetic center and tilt angle adjustments within ±25µm and ±0.1mrad respectively. For the sextupoles, magnetic measurements were performed by the SIGMAPHI Company. This paper presents the main features of the SOLEIL benches, magnetic measurement results in terms of reproducibility, field identity between magnets, magnetic axis centering, and harmonics content versus current.
