| THPE039 | Optimization of dipole-field profiles for emittance reduction in storage rings | 4605 |

Nonuniform dipoles with bending field variation have been studied for reducing storage ring emittance in recent years. According to a new minimum emittance theory, the effects of an arbitrary dipole can be characterized by two parameters. To have a better idea of the potentials of nonuniform dipoles, here we numerically explore the values of these two parameters for optimal emittance reduction. |

|
In this paper, we made a new design for ILC 3.2 km damping ring with 2 arcs based on FODO cell and 2 straight sections which are nearly the same as the new version of the 6.4 km ring DCO4. This new lattice uses less dipoles and quadrupoles than the present SuperB like lattice and has an adequate aperture for the large injected emittance of the positron beam. The work of lattice design and DA optimization will be presented in detail. |
