  We have designed a compact proton synchrotron(7~230 MeV) for applications like proton therapy and space environment study. These applications may require slow extraction from 10~230 MeV. Traditionally, the low energy beam(10~70 MeV) is achieved by energy degradation from high energy beam which may cause beam lose and energy spread increase, because the beam quality may suffer from magnetic remanence, power ripple and strong space charge effects in low energy stage. To achieve high quality beam directly from resonance extraction, we study these effects by performing multi-particle simulation. Methods of improving beam quality are discussed.

  For the Xi'an 200 MeV Proton Application Facility (XiPAF), one important thing is to produce more homog-enous beam profile at the target to fulfill the requirements of the beam application. Here the beam line is designed to meet the requirement of beam expansion and homogenization, and the step-like field magnets are employed for the beam spot homogenization. The simulations results including space charge effects and errors show that the beam line can meet the requirements well at the different energies (from 10 MeV to 230 MeV) and different beam spot size (from 20mm to 200mm).
