TI - Permanent Dipole Magnet R&D for SPring-8-II J2 - Proc. of IPAC2015, Richmond, VA, USA, May 3-8, 2015 C1 - Richmond, VA, USA T2 - International Particle Accelerator Conference T3 - 6 LA - english AB - Permanent magnets are promising for future light source machines with its compactness, small power consumption. We have proposed a variable-field permanent dipole magnet and demonstrated its performance*. Following the result, a prototype magnet with a longitudinal field gradient and a magnetic shunt circuit was designed and fabricated. The longitudinal field gradient enables a lower beam emittance and the magnetic shunt circuit improves a temperature stability of the magnetic field strength. Simulation studies and measurement results are presented in this report. The interference of magnetic fields between neighboring magnets was also investigated.
