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

Abstract

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