  The 3rd resonant slow extraction and RF-Knockout technology has been adopted for XiPAF, which was designed for proton therapy and single event effects. The separatrix of stable region will fluctuate in the process of slow extraction due to power ripple, hence influence the uniform of extracted beam and the extraction efficiency. The influence of dipole and quadrupole power ripple is studied in theory and simulated by a MPI parallel multi-particle program, a method of making beam less sensitive to power ripple is discussed and verified by simulation.
