Abstract

Magnetic measurements have been performed for all dipoles, quadrupoles and sextupoles of the SPring-8 storage ring. The long flip coil and the rotating coil system were used for the measurements and they were good enough in measurement accuracy. Dispersion of the magnetic length and strength of the multipole fields were found to be within tolerable range for the three types of magnet. The position of the fiducial points for alignment was measured in the accuracy of better than 20 μm for all the quadrupoles and the sextupoles
