内容記述 | NIRS has carried out three-dimensional scanning irradiation for carbon-ion radiotherapy at the HIMAC new treatment research facility since May 2011. In this irradiation, we have adopted a raster scan method to make the lateral dose distribution. For the reduction of the difference between prescribed and delivered dose distribution, it is preferable that the extracted beam-current from the synchrotron ring is low ripple, and the response to the beam-on/off switching is quick. To meet these requirements, we have developed a new beam-intensity control system with the RFknockout slow extraction and feedback control system. In the system commissioning, we can modulate the beamintensity in the range of thirty times while keeping the beam-current ripple below 20%. | |||||
