Current status of lattice design and accelerator physics issues of the 3 gev taiwan synchrotron light source

Over the past several years, we have been conducting a design work for a synchrotron light facility with low emittance storage ring in the intermediate energy range at NSRRC. A number of design options with different lattice structure types, circumferences, etc., are explored. We present two design cases, i.e., a 24-cell DBA and a 12-cell QBA structures with 486 m circumference. The associated accelerator physics issues are discussed.
