A new treatment facility project, as an extension of the existing HIMAC facility, has been initiated for the further development of carbon-ion therapy in NIRS. This new treatment facility will be equipped with a 3D irradiation system with pencil beam scanning. The challenge of this project is to realize treatment of a moving target by scanning irradiation. To accomplish practical moving target irradiation and to fix the final design, a prototype of the scanning irradiation system was constructed and installed into existing HIMAC experiment course. The system and the status of the beam test are described.
