Abstract

In addition to previous discussions of the ejection of ions in the direction of the trapping plates by excitation of the cyclotron motion, it is shown that ion ejection also occurs by excitation at 2ωT, twice the trapping frequency, and at 2ωT plus the cyclotron frequency. In all cases, the observed effects can be explained by a simplified expression for the equation of motion in the z-direction.

    Parametric excitation [139] provides a way to stimulate cyclotron (and magnetron) motion without having to cut the side electrodes into segments. If the trapping potential is (as in any actual trap) not perfectly axial, three-dimensional quadrupolar, then axial and radial motions are coupled, and azimuthal dipolar excitation at twice the axial oscillation frequency will excite axial oscillation [140, 141]. This method has been used to eject electrons without having to excite them at their (inconveniently high) cyclotron frequency.
