CURRENT STATUS OF THE 1.5 GEV SYNCHROTRON LIGHT SOURCE IN NSRRC

The current status of the 1.5 GeV synchrotron light source in NSRRC is reported. The machine is operated for approximately 5,000 hours per year, with availability >97%, trip rate <1.5/month and photon beam stability (fluctuation of intensity of photon beam) < 0.1%, during most of the user’s beam time. A superconducting cavity and some superconducting wigglers are constructed to increase beam currents and reduce the instability of high order mode (HOM), and to offer harder x-rays to users. A top-up injection project is initiated to aim for increasing the electron and photon beam stabilities - particularly the mirror stability in the photon beam line. An IR-FEL facility is also planned, in the hope of opening up a new area of IR research. Machine improvements are also discussed herein.
