The storage ring of Taiwan Light Source (TLS) has one Superconducting (SC) cavity, one SC wavelength shifter, and two SC wigglers installed during last two years. The operation mode was also upgraded to have the capability of top-up injection. Top-up is an operation mode in which the beam current is maintained above certain level by frequent injections in the storage ring. The current stability maintains in the range of 10-3 for long period of operation. It provides constant thermal loading on all components in the storage ring and the optics components of beamlines, as well as constant signal to the beam position monitor. The top-up injection is a routine operation mode during user shifts at TLS. Statistics, operation experience and future expansion will be discussed in this paper.

The Taiwan Light Source of National Synchrotron Radiation Research Center (NSRRC) has reached a very stable operation condition and productive scientific outputs. The copper Doris RF cavities were replaced with a niobium Superconducting (SC) RF cavity in order to eliminate higher-order-modes and deliver higher beam current. Superconducting wigglers were installed to provide higher flux at higher photon energy. The storage ring is now operated at 300 mA top-up mode with better than 97 % of beam availability during users shifts. The original layout of the magnets has been greatly modified to accommodate one SC wavelength shifter at the injection section, one SC wiggler at the RF cavity section, and three SC wigglers in achromatic sections in addition to the original design of one wiggler and three undulators. In view of the future scientific demands, the NSRRC is proposing to construct a new synchrotron storage ring of 3.0~3.3 GeV and ultra low emittance, the Taiwan Photon Source (TPS). The TPS will provide brilliant X-rays at 1021 photons/s/0.1%BW /mm2/mr2 by SC undulator upon its completion, making it the brightest synchrotron light with the finest performance in the world.
