Abstract
An ion reflector has a configuration in which multiple plate electrodes having a rectangular opening are arranged. The components are arranged so that a central axial line extending in the longitudinal direction of the opening lies on a plane which contains a straight line (Y-axis) connecting the centroidal position of an ion distribution in an ion trap and a central position on the detection surface of a detector, and a central axial line (X-axis) of an ion-ejecting direction. If the potential distribution along the central axis of the ion reflector is modified so that a portion of the reflecting field becomes a non-uniform electric field intended for improving isochronism for a group of ions to be detected, an area having an ideal potential distribution for realizing the isochronism is spread in the Y-axis direction.
