  The SSRF storage ring is composed of 20 DBA cells with energy of 3.5GeV and circumference of 432m. The installation of the SSRF storage ring was started on June 11, 2007, and finished in the beginning of Dec. 2007. The system tests of hardware and software for storage ring were completed in the middle of Dec. 2007. The commissioning of the storage ring started on Dec. 21, 2007, and the 100mA stored beam was achieved for the first time on Jan. 3, 2008. The design, installation and commissioning of the SSRF storage ring are described in this paper

  The Shanghai Synchrotron Radiation Facility (SSRF) is a 3.5GeV synchrotron radiation light source under commissioning in Shanghai, China. The SSRF accelerator complex consists of a 150MeV linac, full energy booster and a 3.5GeV storage ring. The commissioning of the SSRF storage ring began on Dec. 21st evening, 2007, the first turn and 150 turns was observed in less than 12 hours with RF off and then the stored beam of 5 mA was achieved on Dec. 24th. On Jan. 3rd, 2008, the 100mA stored beam current were obtained in the machine for the first time. Since then, the storage ring has been brought close to the design parameters, and frequent operation with 100mA beam current has been down for making the vacuum chamber cleaning. In this paper, commissioning results of the machine is presented.

  SSRF is a third generation synchrotron radiation light source. It has a full energy injection storage ring of 3.5GeV. The storage ring dipole magnet string and sextupole magnets strings are powered by 10 large magnet power supplies. The power supply output current ranges from 250A to 800A, and the output voltage ranges from 140V to 840V. These power supplies are digital controlled, with bridge topology, and diode rectifiers with step-down transformers. In this paper, the commissioning results of these power supplies are presented, together with the circuit topology and the control schemes.
