SESAME is a 3rd generation synchrotron light source that is optimized for the use of Insertion Devices. In this note, the magnetic design for a Hybrid Multipole Wiggler (HMW) and an Elliptically Polarizing Undulator (EPU), proposed for the Phase-I beamlines of SESAME will be presented. Both devices fulfill the electron beam stay clear requirements defined by the SESAME lattice leading to a decent vacuum lifetime. The HMW will provide photon energies from 3-25 keV, which are defined by the scientific case of the SESAME storage ring. The HMW is a hybrid device with period length of 160 mm, a minimum gap of 14.5 mm, maximum flux density of 2.10 Tesla and total magnetic length of 3.04 m. A maximum photon flux density of 1.80×1015 photons/sec/0.1%BW is obtained. The EPU device is required to provide the SESAME users with a variable polarized light and high photon flux over the energy range of 100-1500 eV. The proposed design is of Apple-II type with a period length of 60 mm, a minimum gap of 13 mm and a total magnetic length of 1.782 m. Only the helical mode of operation has been considered where horizontal, vertical and elliptical polarized light can be obtained.

An update of the status of SESAME is presented. SESAME is a third generation light source facility, with an e-beam energy of 2.5 GeV, located in Allan, Jordan. The emittance is 26 nm.rad and 12 straights are available for insertion devices. The injector consists of a 22.5 MeV Microtron and 800 MeV booster synchrotron, with a repetition rate of 1 Hz. The conceptual design of the accelerator complex has been frozen, and the engineering design is well advanced. The Phase I scientific program for SESAME has also been finalized, and it foresees 6 beam lines, including 2 IR ports. The construction of the SESAME building is in progress, and the beneficial occupancy is expected by the spring of 2007. The completion of the accelerators complex construction is scheduled for 2010.
