Concepts of tunable magnets using permanent magnetic material for synchrotron radiation sources

摘要

Novel tunable magnets using permanent magnetic materials (PMMs) are proposed for the magnetic lattice of the 3 GeV Sinus storage ring. Many essential qualitative aspects are discussed including the low and high field dipole designs using PMMs. Studies for quadruples and sextupoles were also performed, but as an alternative way, which depends on field requirements.
