NSRRC has been operating a 1.5 GeV synchrotron light source, the Taiwan Light Source (TLS), for over 15 years and has established a large user community. For the future development of synchrotron radiation research in Taiwan, a feasibility study report to construct a 3.0 GeV low‐emittance storage ring, the Taiwan Photon Source (TPS), was issued in July 2005. The government approval of the TPS project was obtained in December 2007 and the machine will be built at current site of NSRRC. The project has progressed steadily since and reached several major milestones now: the architect firm has finished the site plan and civil design, the accelerator design has been fixed, and purchase of long‐lead items begins its course. The TPS storage ring has a circumference of 518.4 meters with a concentric booster of 496.8 meters. The storage ring adopted a 24‐cell double‐bend structure with a 1.6 nm‐rad natural emittance. There are six 12‐m and eighteen 7‐m ID straights. For user research, five new beamlines have been selected for the Phase I operations: the micro protein crystallography, the materials sub‐micron diffraction, the inelastic soft x‐ray scattering, the coherent x‐ray scattering, and the nano probe beamlines. The civil construction is getting ready to start. The commissioning of the TPS storage ring is targeted for 2013.
