Magnet lattice for the Siam Photon Source

Abstract

The magnet lattice for the Siam Photon Source, the ®rst 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 % 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.

The Siam Photon Laboratory

“…Experiments carried out with the newly built experimental stations will be used to train young scientists in state-of-the-art science, particularly in the ®elds of physics, chemistry and materials science. A beam-dynamics calculation of the modi®ed storage ring has been carried out (Kengkan et al, 1998). The results show that the dynamic aperture is wide enough for the electron beam to be stored in the ring easily.…”

Design of the first undulator beamline for the Siam Photon Laboratory

“…The Siam Photon Source (SPS) [1] has been providing synchrotron radiation from bending magnets since the start of its operation. A planar undulator purchased from Danfysik [2] is the first insertion device to be installed to provide high radiation brightness in the VUV/soft X-ray region.…”

X-Rays at the SIAM Photon Source

“…The SIAM Photon source is a 1 GeV storage ring with a circumference of 81.3m including four long straight sections for insertion devices [1] (Fig. 1).…”
