	In order to provide synchrotron light with higher photon energy and more brilliant synchrotron light than that of the existing Siam Photon Source (SPS) machine, the possibility of constructing the new 3 GeV SPS-II has been proposed. For SPS-II, the synchrotron source with in-tunnel booster is a good candidate. The booster synchrotron has been designed in order to accelerate an electron beam of 150 MeV to 3 GeV before extracted to storage ring. For a clean injection in top-up operation, the aim in the design of the booster is to achieve the electron beam with a small emittance less than 10 nm-rad and to obtain a large dynamic aperture. The energy ramping process and related effects during the energy ramp are discussed in this paper.

The storage ring includes 14 long and 14 short straight sections for insertion devices and machine subsys-tems. The beam injection will be performed by a 150 MeV linear accelerator and a full-energy concentric booster synchrotron sharing the same tunnel with the storage ring. In the first phase, there will be 7 insertion devices and 7 associated beamlines with the end sta-tions for different techniques utilizing synchrotron radiation from 80 eV to 60 keV. High-energy and high-brightness radiation generated by the new light source will serve as one of the most powerful analytical tools in the region for advanced science and technology research.
