Abstract :
Prototypes of a dipole, a quadrupole, and a sextupole magnet for the SPring-8 storage ring have been built. Their fields were measured with four types of field measurement equipment. Their excitation curves, effective lengths, and strengths of higher multipole fields were determined. On the basis of the measurement results, design was modified with the aim of reducing production and operation costs
