Dipole and Quadrupole Magnets for the Duke FEL Booster

The full energy booster injector for the Duke FEL storage ring is presently under installation [2]. The booster is designed to provide continuous injection into the Duke FEL storage ring in top-off mode at the energy variable from 0.27 GeV to 1.2 GeV. The magnetic elements for the booster have been fabricated and magnetically measured at Budker Institute of Nuclear Physics, Russia. The paper presents magnetic and mechanical design of the booster dipole and quadrupole magnets and results of their magnetic measurements. Results of simulation of the booster lattice taking into account residual field and non-linearity of the magnets are also presented.
