摘要
Beam emittance reduction is an effective method to increase the brightness of a synchrotron light source.Robinson wiggler can play a role in the beam emittance reduction by increasing the horizontal damping partition number.A replacement of the quadrupoles in the arc section with short combined function dipoles will construct a single-periodic Robinson wiggler in the SSRF storage ring.This scheme provides a lower beam emittance,without occupying any straight section.Detailed analysis is presented in this paper.
