Lattice Study for the Taiwan Photon Source

The feasibility study for the new 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 around 2 nm-rad. A large booster ring of 499.2 m sharing the storage ring tunnel as well as a separated booster ring of 162 m are considered.
