摘　　要：We report on a new design for an ILC 3.2 km damping ring,with 2 arcs based on the FODO cell and 2 straight sections that are nearly the same as the newest version of the 6.4 km ring DCO4.This new lattice requires fewer magnets and a lower RF voltage, and has a better dynamic aperture than DCO4 while maintaining flexibility in regard to the momentum compaction factor.So far, this design is the only one satisfying all the requirements for a 3.2 km ring.The work on the lattice design and the dynamic aperture study is presented in detail.We report on a new design for an ILC 3.2 km damping ring, with 2 arcs based on the FODO cell and 2 straight sections that are nearly the same as the newest version of the 6.4 km ring DCO4.
