	It's important to control the beam position for the 3D pencil-beam scanning because the position accuracy of the beam has a serious matter on the alignment of the irradiation field. In order to suppress this matter, we have been developed a simple procedure for the beam tuning. The fluctuation of the beam position is tuned with the steering magnets (ST) and the fluorescent screen monitors (SCN). At first, the beam positions are measured by two SCN and the kick angles of two ST are calculated using deviates from the center of the beam position measured by SCN and the transfer matrix. After the tuning, the beam position at the isocenter is checked on the verification system for the alignment of the beam consists of the SCN and the iron sphere phantom. If the beam position is deviated from the center, one of ST placed on most downstream of the beam transport line will be corrected. These adjustments are iterated until the deviation for all energies of the beam are within 0.5 mm. We have been performed the beam commissioning using our procedure in Kanagawa Cancer Center. In this presentation, we will report on the result of these measurements.

	As part of the Kanagawa "Challenge-10-year strategy to cancer" it was decided in March 2005 to establish a carbon-ion therapy system at the Kanagawa Cancer Center (KCC). From around 2009, the basic design and the foundational planning of the facility were considered and in January 2012 a contract was made with the Toshiba Corp. In December of the same year, construction of the main building for the acceleration and treatment devices has been started and completed in October 2014. Currently, the KCC is in a commissioning phase with the aim to start treatment in December this year. Various treatments for cancer, which include four present photon LINAC for the radiation therapy, will be provided to patients in cooperation with our cancer center hospital. In addition, we will combine a compact dissemination treatment system of carbon-ion therapy to the pencil beam 3D scanning technique designed by the National Institute of Radiological Sciences (NIRS). The treatment experience with the carbon-ion scanning technique is expected to be the second in the country following NIRS. In this presentation, we will report on the progress of the beam commissioning of the scanning system.
