Abstract：
After upgrade of the Hefei light source, the optics parameters of electron storage ring were adjusted and measured. Both the kicker and the RF system were reconstructed completely, and were commissioned well. The SVD algorithm is used for the global closed orbit feedback. Two methods were used to suppress the transverse coupled bunch instability. So a 300mA beam intensity is achieved.
