 note = {To make the best use of the characteristics of a carbon-ion beam and provide flexible dose delivery, three-dimensional (3D) pencil-beam scanning is an ideal irradiation technique. As part of the efforts to achieve ion-scanning therapy, a new treatment facility equipped with a 3D scanning irradiation system was constructed as an extension to the existing HIMAC. The 3D scanning irradiation system has been utilized for treatment since 2011. At present, for depth direction, the hybrid depth scanning method has been employed, in which 11 beam energies ranging from 140 to 430 MeV/u are used in conjunction with the range shifter. To suppress the beam spread due the multiple scattering and the nuclear reaction, we have developed a full energy scanning method (FES). In FES, we prepared more than 200 energy steps with 1 or 2 mm intervals. To obtain the range of less than 1 mm without using an energy absorber such as a range shifter, the minimum energy is chosen as 55.6 MeV/u. Generally, a long time is required for accelerator tuning and beam commissioning tests for treatment by FES. In our presentation, we introduce the beam commissioning for FES in a short period of time and the performance of FES is evaluated., The 12th European Conference on Accelerators in Applied Research and Technology (ECAART12)},
