Description
Carbon-ion radiotherapy has been carried out at Heavy Ion Medical Accelerator in Chiba (HIMAC) in National Institute of Radiological Sciences (NIRS) since 1994. NIRS started three-dimensional scanning irradiation using a pair of deflection magnets and energy-degrading plates with various thicknesses from May 2011. In addition, NIRS plans to employ a multiple-energy synchrotron operation for scanning irradiation from September 2012. This operation enables us to change the extracted beam-energy quickly and to avoid use of thick energy degraders which broaden the beam spot size. We have improved the existing HIMAC extraction system for the multiple-energy operation. In the commissioning of variable beam-energy extraction, we verified that the improved system meets the requirements for performing irradiation with pencil beam scanning. (author)
