  The slow extraction beam from HIRFL-CSR is used in nuclear physics experiments and heavy ion therapy. 50Hz ripple and harmonics are observed in beam spill. To improve the spill structure, the first set of control system consisting of fast Q-magnet and feedback device based FPGA is developed and installed in 2010, and spill structure feedback test also has been started. The commissioning results with spill feedback system are presented in this paper.
