The RF-KO slow-extraction method has been used for fast on/off switching of the beam from the synchrotron during scanning irradiation at HIMAC. However, the controllable low beam rate is limited by a small amount of beam which spilled out without the transverse RF field. We could reduce it to 0.4 % compared to the original method by adding the another transverse RF field.
