  • Publication number: 20210296108
    Abstract: An ion guide (222) is for use in transport of an ion incident from an upstream side toward a downstream side. The ion guide includes 2n rod electrodes (n is an integral number greater than or equal to 2) equally spaced and surrounding an ion optical axis (C) that is a central axis of a flight path of the ion, a voltage applying unit (30) that applies a radio-frequency voltage to the 2n rod electrodes, and a controller (43) that controls the voltage applying unit (30). The controller (43) prompts the voltage applying unit (30) to apply a radio-frequency voltage that generates, in a space surrounded by the 2n rod electrodes, an electric field which is a 2n-multipole electric field superimposed by a higher-order electric field component than the 2n-multipole electric field.

  • Patent number: 10707066
    Abstract: Four main rod electrodes included in a main electrode section are disposed in a rotationally symmetric manner around an ion optical axis. Among four pre-rod electrodes included in a pre-electrode section disposed in front of the main electrode section, two are in contact with a circle of a radius r0, whereas the other two are disposed to be in contact with a circle of a radius R0 larger than r0, resulting in rotational asymmetry around the ion optical axis. Accordingly, a shape of acceptance on an x-y plane regarding positions of ions in the pre-electrode section becomes elliptical. This allows the shape of the acceptance to become gradually flat as the ions travel along the ion optical axis, reducing a mismatch between emittance of incoming ions and the acceptance on a receiving side, and relieving ion loss during ion introduction.
