| 发明名称 | Energy degrader and charged particle irradiation system including the same | ||
| 摘要 | An energy degrader includes: a damping unit that attenuates energy of incident charged particles and has a thickness changing stepwise or continuously according to a position of a two-dimensional coordinate system within a plane crossing a traveling direction of charged particles; and a driving unit that performs translational driving of the damping unit in first and second axial directions that are directions of two axes crossing each other in the two-dimensional coordinate system. | ||
