  Dipole field kicks arisen from the construction and alignment of the magnets may cause the orbit distortion and reduce the efficiency of beam extraction and striking target in RTBT transport line of CSNS. In this paper, orbit correction is done based on XAL Orbit Correction application with the algorithm modified partially and the result was according with by AT toolbox. Meanwhile, the orbit correction before the target was special considered for the beams striking the target center vertically.

  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.

In this paper we will show a genral method of how to make an optimized parameter design of a circular e+e Higgs Factory by using analytical expression of maximum beam-beam parameter and beamstrahlung beam lifetime started from given design goal and technical limitations. A parameter space has been explored.
