Accelerator Physics Issues for the TPS

Taiwan Photon Source (TPS) is a 3 GeV low emittance 3-generation light source currently under construction at the NSRRC site in Taiwan. TPS consists of 24 double-bend cells and its circumference is 518.4 m. A 496.8-m booster with multi-bend structure is designed. In this paper, we present the accelerator physics issues including nonlinear optimization, Touschek lifetime estimation, orbit and coupling corrections, effects of insertion devices, impedance and instabilities, alterative lattice configurations and booster injector.
