 note = {Control of the beam position for three-dimensional pencil-beam scanning is important because the position accuracy of the beam significantly impacts the alignment of the irradiation field. To suppress this effect, we have developed a simple procedure for beamline tuning. At first, beamline tuning is performed with steering magnets and fluorescent screen monitors to converge beam’s trajectory to central orbit. Misalignment between beam position and reference axis is checked by the verification system, which consists of the screen monitor and acrylic phantom. If the beam position is deviated from the reference axis, two pairs of steering magnets which are placed on downstream of the beam transport line will be corrected. These adjustments are iterated until the deviations for eleven energies of the beam are within 0.5 mm of the reference axis. To demonstrate the success of our procedure, we performed beam commissioning at the Kanagawa Cancer Center using our procedure., The 12th European Conference on Accelerators in Applied Research and Technology (ECAART12)},
