  The feasibility study for the new 3.0~3.3 GeV Taiwan synchrotron light source, dubbed Taiwan Photon Source, was initiated in July, 2004. The goal is to construct a high performance light source with extremely bright X-ray in complementary to the existing 1.5 GeV light source in Taiwan. The ring circumference is 518.4 m and a 24-cell DBA lattice structure is chosen. The natural emittance with distributed dispersion is less than 2 nm-rad. A large booster ring of 499.2 m sharing the storage ring tunnel will be adopted.

  After more than 10 years' operation and expansion, the Taiwan Light Source (TLS) of National Synchrotron Radiation Research Center (NSRRC) reaches very stable operation condition. The storage ring has better than 96% of beam availability annually with 6 Insertion Devices (ID) in a six-folds symmetry over-crowded machine. Two superconducting IDs and one superconducting RF cavity were installed in recent year, which intend to push the photon energy to hard x-ray regime and double the photon flux with better beam quality. Beamlines and experimental stations occupied all over the experimental area. The uproar for more beamlines in higher photon energy with higher brightness was frequently transpired from users' community. The Board of Trustee of NSRRC gave a green light to a new design and construction of median-energy light source, Taiwan Photon Source (TPS) in the coming decade. This paper will present two draft designs of booster and the consideration of the design criteria for new booster to work with a top-up injected and very low-emittance storage ring.
