The Shanghai Synchrotron Radiation Facility (SSRF), a 3.5GeV storage ring based third generation light source, started its user operation with 7 beamlines in May 2009. During the passed year, the facility reliably operated about 4000 hours for user experiments. This paper presents the operational status of the SSRF in the first year and its future performance improvement plans.

The construction of SESAME, a 2.5 GeV, and 3rd generation synchrotron-light source is under progress. The first electron beam from the Microtron at low energy (less than 10 MeV) could be obtained on July, 14th, 2009 and reproduced several times. The tests of the injection and extraction system as well as the hydraulically and electrical tests of the main magnets of the Booster are complete and the vacuum chambers tests are underway. The Booster RF cavity and its plunger have been conditioned successfully by 1.7 kW CW RF power. The installation of the Booster is expected to start after the completion of the shielding. The design of the completely new storage ring is finalised and the Phase 1 beamlines is updated.

The Novosibirsk ERL has rather complicated magnetic system. One orbit (11-MeV) for terahertz FEL lies in the vertical plane. Other four orbits lie in the horizontal plane. The beam is directed to these orbits by switching on of two round magnets. In this case electrons pass through RF cavities four times, obtaining 40-MeV. At the 4th orbit the beam is used in FEL, and then is decelerated four times. At the 2nd orbit (20 MeV) we have a bypass with another FEL. When bypass magnets are switched on, the beam passes through this FEL. The length of bypass is chosen to provide the delay necessary to realize deceleration at the3rd pass through accelerating cavities. In 2008 two of four horizontal orbits were assembled and commissioned. The electron beam was accelerated twice and then decelerated down to low injection energy. First multi-orbit ERL operation was demonstrated successfully. In 2009 the first lasing at the second FEL, installed on the bypass of the second track, was achieved. The wavelength tunability range is 40 - 80 micron. Energy recovery of a high energy spread used electron beam was optimized. Third and fourth orbit assembly is in progress.
