<p>The present invention comprises: an accelerator (2) which accelerates charged particles and emits a charged particle beam; a gantry (4) whereupon is positioned an illumination part (3) which illuminates a subject to be illuminated with the charged particle beam; a conveyor line (6) which conveys the charged particle beam from the accelerator (2) to the illumination part (3), further comprising an energy selection system (8) which extracts from a charged particle beam with a first energy width which is emitted from the accelerator (2) a charged particle beam with a second energy width which is smaller than the first energy width; and a structure (100) further comprising an illumination chamber (A) in which the gantry (4) is positioned, and a conveyor chamber (B) in which a portion of the conveyor line (6) is positioned. The accelerator (2) is positioned in the illumination chamber (A), and the energy selection system (8) of the conveyor line (6) is positioned in the conveyor chamber (B). The structure (100) further comprises a partition (101) which separates the illumination chamber (A) and the conveyor chamber (B), and blocks off radiation which is emitted from the energy selection system (8).</p> |
