STUDY OF THE SYNCHROTRON AND BETATRON OSCILLATIONS FOR THE SIAM PHOTON SOURCE

The storage ring in the Siam Photon Source of National Synchrotron Research Center, THAILAND is the upgraded version of SORTEC storage ring. The magnet lattice structure is changed to obtain the low emittance and to include the long strai ght sections to provide space for the insertion devices. Therefore, a detailed analysis of the modified parameters of the synchrotron and betatron oscillations in longitudinal and transverse phase space, respectively have been carried out by developing the computer programs using the visual basic. The dynamics of electrons making synchrotron motion in the presence of RF accelerating field and radiation damping of synchrotron and betatron oscillations have been studied for the storage ring in the Siam Photon Source. Parameters such as the synchrotron oscillation frequency, the momentum acceptance of the RF acceleration system, the maximum phase deviation, damping times for the synchrotron and betatron oscillations have been evaluated.
