Abstract The heavy ion beam from Heavy Ion Research Facility in Lanzhou (HIRFL) CSR Main Ring (CSRm) is slowly extracted by using a third-order resonance driven by sextupole magnets and delivered to various experimental facilities. The slow extraction is driven by the transverse radio frequency knockout (RF-KO) exciter. Many physics and radiation medicine experiments require high-quality spill-structure. In other words, the extracted spill should have flat structure and low ripple noise [1]. Therefore, a novel RF-KO exciter and spill feedback control system has been implemented and tested in CSRm.
