The 1.5 GeV operation parameters and performance at SRRC

The storage ring at SRRC is highly promising as an ultraviolet to soft X-ray radiation source for use in basic research and industrial applications. Energy ramping of the storage ring can push the critical photon energy to the edge of hard X-ray. The tune drifting, during the ramping procedure, is expected and should be minimized such that the beam can survive through the ramping process. The betatron frequencies and the ramping function of magnets were carefully monitored in order to avoid the betatron tunes crossing the fatal resonance line. A successful ramping results and lattice parameters were measured and discussed in this paper. The measured photon flux increased by six to seven folds at the X-ray beam line. Life time reaches 9 hours of 200 mA beam current.
