Description
Siam Photon Source II (SPS-II) is a 4th-generation synchrotron light source to be constructed in Thailand, envisioned as a major synchrotron facility for Southeast Asia. It is designed with a 3 GeV low-emittance electron storage ring based on a Double Triple Bend Achromat (DTBA) lattice, with a circumference of 327.6 meters and a natural emittance of 0.97 nm·rad. The design and machine parameters have recently been carefully revised to enhance beam stability and operational reliability. In parallel, key prototypes are being developed to support smooth construction and ensure long-term performance. This paper presents the detailed specifications and a comprehensive overview of the planned beam diagnostics and instrumentation systems, along with initial results from their ongoing R&D and testing.
