Abstract

In this paper we present a project of a Booster-injector for the Duke FEL storage ring. The Booster will provide full energy injection into the storage ring at energy from 0.25 to 1.2 GeV. The Duke storage ring FEL (SR FEL) operates in lasing mode with 193-700 nm wavelength range. This range will be extended into VUV in near future. The geometry of the Duke SR FEL provides for head-on collision of e-beam and FEL photons. This mode of operation is used for High Intensity γ-ray Source (HIγS facility) generating intense beams of γ-rays from 1 MeV to about 200 MeV (currently from 2 MeV to 58 MeV). Generation of γ-rays with energy exceeding 20 MeV causes the loss of electrons, which will be replaced by new electrons from the Booster, operating in a top-up mode. The Booster has a robust FODO lattice. In this paper we present the design of the Booster and its magnetic elements. For 2D and 3D magnet design of the magnetic elements we used MERMAID 2D/3D code
