RESUMEN
A synchrotron radiation research project, the Siam Photon Project, is underway in Thailand. The light source used in the project is the modified SORTEC storage ring. The project and simple aspects of the light source are described. The detailed design of the building to accommodate the experimental hall and the light source has been accomplished and the construction will start soon. The engineering design work of the machine components necessary for the modifications to reduce the beam emittance and to make the installation of insertion devices possible is underway.
RESUMEN
The magnet lattice for the Siam Photon Source, the first storage ring for synchrotron radiation research in Thailand, has been designed. The storage ring has a double-bend achromat lattice and fourfold symmetry with four straight sections. Although the magnet lattice is relaxed, an emittance value of 72 pi nm rad has been obtained, which is only 1.4 times as large as the theoretical minimum emittance with eight bending magnets. The dynamic aperture is found to be much larger than the physical aperture.
