 note = {The time structure of extracted beams has been improved in synchrotron rings with resonant slow-extraction
including RF-knockout extraction.In order to control the global spill structure in the RF-knockout slow-extraction
method,it is necessary to improve the amplitude modulation (AM)function of the transverse RF-field.For this
purpose,a scheme with a simple model of the extraction process has been proposed.Using this simple model,an
analysis was carried out for determining the parameter relevant to the diffusion process in the separatrix.With this
parameter,the new AM function obtained by the analytical approach could provide a flat spill within 7 in both a
simulation and an experiment at the HIMAC synchrotron.Cooperating with the feedback system,the global spill
structure was signi ficantly suppressed to be less than 7 .},
