TLS and TPS at National Synchrotron Radiation Research Center (NSRRC)


Located in the Hsinchu Science Park, Taiwan, the National Synchrotron Radiation Research Center (NSRRC) is a non-profit research organisation, funded by Taiwan’s Ministry of Science and Technology (MOST). NSRRC currently operates two synchrotron light sources, namely the Taiwan Light Source (TLS) and the Taiwan Photon Source (TPS), providing users with 31 beamlines including the two Taiwanese beamlines at SPring-8, in Japan.
TLS with a beam energy of 1.5 GeV and a circumference of 120 m, was the first, third-generation synchrotron light source facility established in Asia and the third globally. Over 50 experimental stations on 24 beamlines operate in the TLS, which began user operation in 1993.
TPS with a circumference of 518.4 m, is equipped with a low-emittance synchrotron storage ring and a booster ring in the same tunnel producing a beam of 3 GeV. It has a capacity of about 40 beamlines; five of the initial seven beamlines are now open to users, and nine phase-II beamlines are in commissioning or under construction. As one of the brightest synchrotron light sources in the world, TPS has the energy spectrum ideal for x-ray sciences, accelerates scientific progress and opens research with synchrotron radiation to more diverse fields, especially biomedicine and nanoscience technologies.
TPS has 7 phase-I beamlines constructed, 9 phase-II beamlines in commissioning or under construction, and 9 phase-III beamlines under planning.

  • TLS opened to users since 1994 and TPS more recently in 2016.
  • Every year NSRRC hosts around 13,000 academic user visits; approximately 10% are international.
