Guiding of 105 keV Ar7+ Ions through a Gap Formed by a Paired Parallel Glass Plates

    Graphical Abstract
    • Abstract
  • The transmission of 105 keV Ar7+ ions with high incident current (about 80 nA) through the gap formed by a paired parallel glass plates was investigated. The intensity and angular distribution of the transmitted ions for various tilt angles were measured using a onedimensional position sensitive detector. The results indicate the existence of a guiding effect when Ar7+ ions pass through the gap， but it is different from that for ions passing through nonacapillaries. We found a measurable dependence of the full width at half maximum (FWHM) of the transmitted ions as a function of the tilt angle. In addition， when the gap was tilted with respect to the direction of the incident beam， the observation angle related to the center of the transmitted ions profile was not equal to the tilt angle.
