  SESAME (Synchrotron Radiation Light Source in Allan, Jordan) consists of an 800 MeV injector (original from BESSY I, Berlin, Germany) and a 2.5 GeV storage ring. Extraction out of the Booster is done by means of a bumper, a delay-line kicker, and a direct driven in-vacuum septum. This paper will present the injection procedure into the storage ring. Simulations of the injection process are compared to the results obtained during commissioning

  SESAME light source uses a 2.5GeV storage ring, designed to produce synchrotron light in the hard X-ray region. The 133.2 m circumference ring composed of 16 Double Bend Achromat cells with 16 dispersive straight sections, offers a maximum capacity of 25 beamlines. The storage ring is filled with electrons using an 800MeV injector of 1 Hz repetition rate. This article reports on the main results and first experience of storage ring commissioning and operation.

  SESAME the Synchrotron Radiation Light Source in Allan (Jordan) consists of an 800 MeV injector (original from BESSY I, Berlin, Germany) and a 2.5 GeV Storagering. Injection into the Booster is done by an electrostatic Septum and one stripline kicker. Extraction out of the Booster is done by means of a bumper magnet, a strip-line-line kicker and a direct driven in-vacuum septum. Injection into the Storagering is done by a direct driven out-off vacuum septum and one kicker. The pulses of all septa are full sine, the ones of the kicker half sine with exception of the extraction kicker (flat-top). Extraction Kicker and Storage ring injection kicker are switched by Thyratron, all others via transistors. This report describes the injection and extraction optics and the results of the commissioning.

  SESAME is the first synchrotron light source for the Middle East and is expected to start its operation mid-2017. It is composed of a 22 MeV Microtron, a 0.8 GeV booster synchrotron and a 2.5 GeV storage ring. The storage ring magnets and power supplies were designed, produced and validated under the framework of a collaboration between SESAME and CERN, supported by the European Commission. The power supply control strategy for the SESAME main ring follows the same model used in the LHC, where the power supplies are voltage sources bought from industry, to which a specially designed control unit and current sensors are added to implement a high precision current source. This strategy provides modularity, ease of maintenance, better control over performance and flexibility for the machine. Machine flexibility is further enhanced by individually powering the quadrupole magnets. In this paper, the powering strategy, design and validation of the magnet power supplies are described. Some of the challenges faced during those phases are discussed. Finally, performance results are presented, showing stability of the dipole power supply at nominal current of about 10 parts per million.
