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 beam lines, we start design and construction of a  superconducting rotating gantry. The construction of rotating gantry is completed in September 2015. This gantry can provide the beam energy ranging from 50 to 430 MeV/u. Since the rotating gantry system requires that the beam profiles at the iso-center have no correlation between the rotation angles, we employ thin scatter method. After the commissioning of beam transport line, we have started the commissioning of PBS system. Our PBS system is designed to treat moving target with fast rescanning as same as that of fixed beam line. In this presentation, we will report the present status of commissioning of our gantry and related beam tests., The 55th Annual Conference of the Particle Therapy Co-operative Group (PTCOG55)}, title = {Commissioning of rotating gantry and scanning system at NIRS-HIMAC}, year = {2016} }
