The proton irradiation accelerator is widely founded for industry application, and the extracted beam is required to have large intensity as a pulse beam or uniform distribution for scanning. A multi-turn injection is adopted and the proton beam is injected into the ring with the energy of 10MeV. In order to increase injection beam intensity, local bump orbit including two-bump, three-bump and four-bump is well studied and optimized, and the septum magnet thickness and localization are also studied for an effective injection. A RF knock-out method is used for slow extraction due to the fast response character. In order to decrease the global spill, double RF kicker and the control of the aptitude modulation (AM) function of the transverse RF field are well studied.
