| 内容記述 | Abstract 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 RF-knockout slow extraction and feedback control system. In the system commissioning, we can modulate the beam-intensity in the range of thirty times while keeping the beam-current ripple below 20%. |
