Introduction SESAME is a joint 3rd generation light source being constructed in Jordan (in Allan, 30km west of Amman) for the Middle East and expected to serve the user community starting from the 1st half of 2017. SESAME machine consists mainly of: 800 MeV injector (22.5 MeV classical Microtron MeV Booster) (BESSY I injector). completely new hard X-ray storage ring with energy 2.5 GeV. maximum number of 25 beamlines.

Injector Commissioning is Done: Booster
Ibeam = 4 mA (~ 5% injection efficiency) was achieved for the best shots. The varying injection efficiency is due to instability in the electrostatic injection septum. Ibeam = 7-8 mA (8-9% injection efficiency) was recently achieved by compensating beam loading effect using RF Fast Feedback Loop. M.

Storage Ring Status: Magnets
Storage ring magnets are constructed through CESSAMag project in the frame of SESAME-CERN/EU collaboration (big support from EU and CERN) Dipoles are constructed by TESLA (UK) and magnetically measured at ALBA light source (Spain). Quadrupoles are constructed by Elytt (Spain) (coils by STS-Turkey) and magnetically measured at CERN. Sextupole are constructed by CNE (Cyprus) & HMC-3 (Pakistan) (coils by SEF-France) and magnetically measured at CERN. All magnets have been delivered to SESAME. M. Attal, Fusion Device & Accelerator Business Meeting, May , BEXCO Building, Busan, Korea

Storage Ring Status: RF System
The 500 MHz RF system is composed of 4 RF plants. Each plant consists of: kW Elettra cavity (detuned up to ±2MHz). Collaboration agreement was signed with Elettra. 2 M€ donation from Italy (4 RF cavities). Delivery of 4 cavities to be completed by Sep - 80 kW solid state amplifier(the 1st is built by SOLEIL, the 3 others by Sigmaphi-SE). Two amplifiers have been constructed. Delivery of 4 amplifiers to be completed by Sep - WR1800 waveguide (in-kind contribution from DESY) - Digital LLRF is constructed by Dimtel-LLRF (to be delivered soon) SSA-SOLEIL M. Attal, Fusion Device & Accelerator Business Meeting, May , BEXCO Building, Busan, Korea
