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 38 beamlines including the two Taiwanese beamlines at SPring-8, in Japan.

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

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. Currently, around 50 experimental stations on 22 beamlines operate in the TLS.

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; 7 phase-I and 9 phase-II beamlines are now open to users while others are in commissioning, under construction or under planning. 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.
