    摘要: The present invention relates to a gantry with an ion-optical system comprising: a first bending magnet for bending an ion beam off an axis of rotation of said gantry; a second bending magnet for bending said ion beam parallel to said axis of rotation; a third bending magnet for bending said ion beam toward an intersection of said ion beam with said axis of gantry rotation; a horizontal scanner magnet for horizontal scanning of said ion beam in a plane perpendicular to the beam direction; a vertical scanning magnet for vertical scanning of said ion beam in a plane perpendicular to the beam direction; at least six quadrupole magnets with adjustable excitation which provide a fully achromatic beam transport from the gantry entrance to the isocentre; a control of the size of said ion beam in the isocentre wherein the gantry can be rotated by any angle between 0° and 360° and the ion beam entering said gantry has different emittances in the horizontal and vertical planes.
