| 内容記述 | Objective: At Heavy Ion Medical Accelerator in Chiba (HIMAC), more than 8000 patients have been successfully treated by carbon ion beams since 1994. The successful results of treatments have led us to construct a new treatment facility equipped with a three-dimensional pencil beam scanning (PBS) irradiation system. After the construction of fixed ports, we start construction of a superconducting rotating gantry. This isocentric rotating gantry can transport heavy ions with the maximum energy of 430 MeV/u, and is capable of performing 3D PBS. Methods: Based on the experience of fixed port, in new nozzle design for the gantry, we focus on the realization of smaller beam size. For this purpose we developed new beam monitors and ripple filters. These new devices are designed to suppress the beam broadening due to multiple scattering. Further, for same reason, the locations of these devices are designed to be closer to the isocenter. The preliminary performance evaluation was performed using the scanning beam from the fixed port. Results: These new design and related beam studies are almost completed. Throughout the beam test, the validity of the design was confirmed. Conclusion: In this presentation, we will report the present status of these new devices and related beam tests. |
