The Synchrotron Light Research Institute (SLRI) is a Public Organization funded by the Ministry of Science and Technology, Thailand.
SLRI is located in Nakhon-Ratchasima, 250 km from Bangkok. The institute has operated a 1.2GeV storage ring so-called the Siam Photon Source (SPS) since 2003. Originally, this synchrotron source was built and used for lithography application in Japan by the SORTEC corporation before the donation to Thai government in 1996. The storage ring was re-designed for 1.2GeV with magnet lattice of Double Bend Acromat (DBA). The new design allows 4 insertion devices (IDs) to be installed in 4 straight sections. Currently, 3 IDs including Undulator (U60), Superconducting Wavelength Shifter (SWLS 6T) and Multipole Wiggler (MPW 2.2T) have been installed.
The storage ring is currently operated in decay mode giving 2 shifts/day for experiment. Facility opens 2 cycles/year, January to May and September to December, respectively.

To expand the research capacity, SLRI aims to upgrade current synchrotron source to the new generation of 3 GeV Energy.
