A particle therapy system is provided. The particle therapy system includes a rotatable gantry with a gantry wall that surrounds an interior. A small irradiation chamber, with an irradiation chamber wall, is located inside the interior. The irradiation chamber wall is spaced apart from the gantry wall, and a deflection chamber is embodied between the two walls. The irradiation chamber wall includes a plurality of wall elements, which to enlarge the irradiation chamber are adjustable in the direction of the deflection chamber, for example, when positioning a treatment table in the small irradiation chamber, such that an opening in the irradiation chamber wall is created.
