  Several major upgrades have been integrated into routine operation in Taiwan Light Source (TLS). Top-up injection mode was achieved after series of efforts to upgrade the injector, transfer line and injection components. The operation current of Top-up injection has reached 300 mA during users shift. The commissioning of the first and second Superconducting RF cavities (SRF) was very successful and exceeded the specification in several measures. The first In-Archromat Superconducting Wiggler (IASW) was installed and commissioned successfully. The associated beamlines will be commissioned in the second half-year of 2006. A 3 GeV low emittance light source has been proposed as the next major upgrade. Intensive design efforts are in progress.

  After more than 12 years of steady operation and expansion, the Taiwan Light Source (TLS) of National Synchrotron Radiation Research Center (NSRRC) has reached a very stable and productive operation condition. In 2004, a major upgrade took place in which the original copper Doris RF cavities were replaced with a niobium superconducting RF cavity in order to eliminate higher-order-modes and deliver higher beam current. In 2005, the top-up injection mode was also successfully implemented. The storage ring is now operated at 300 mA top-up mode with better than 98% of beam availability to the users community. With a small size (120 m) circumference of the six-fold ring, the original layout of the magnets has been greatly modified to accommodate one superconducting wavelength shifter at the injection section, one superconducting wiggler at the RF cavity section, and three superconducting wigglers in achromatic sections in addition to the original design of one wiggler and three undulators. The TLS can now provide high photon flux to cover a whole spectrum of infrared, vacuum ultra violet, soft X-ray, and hard X-rays for advanced experiments. Currently, TLS has 28 beamlines and over 54 experimental stations in operation for many different scientific researches. The user body is reaching twelve hundreds. 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). A feasibility study of TPS has been completed and submitted to the National Science Council for evaluation.
