Scientists nationwide and all over the world have been swarming in to conduct pioneering scientific research which resulted in remarkable growth in both the research quality and quantity that leveled up to the world standard. However, in order to cope with the increasing demand for brighter synchrotron x-ray source for top-notch research, the immense competition in the international scientific arena, and the rapid development of the world’s synchrotron light source community, domestic scientific community has pushed for the next generation of synchrotron light source, the Taiwan Photon Source (TPS). Through many great efforts, the TPS team has overcome the bottlenecks on the accelerator design and the civil design. The contracting of the civil construction and the procurement of major items are now on the way. TPS is scheduled to become operational in 2013. We hope TPS can offer one of the world's brightest synchrotron x-ray sources, provide cutting-edge experimental facilities and novel multidisciplinary scientific research opportunities, enhance world-class academic research, as well as create Taiwan's scientific research marvels in the twenty-first century. 3 GeV 400 mA at 3 GeV (300 mA in 1st-phase) 518.4 m (h = 864) 496.8 m (h = 828 ) 24-cell DBA 12 m x 6 ( σv = 9.8 μm, σh = 165.1 μm) 7 m x 18 ( σv = 5.1 μm, σh = 120.8 μm) 1.7 nm·rad at 3 GeV (Distributed dispersion) 500 MHz 6.4 MV (4 SRF cavities) 720 kW (4 SRF cavities)
