      <text>Method of ion detection by measuring the current that results from the image charge induced by a coherent motion of ions passing near a conductor.</text>
      <notes>
        <item>In Fourier transform mass spectrometers or Kingdon traps, the coherent orbital motion of ions between a pair of electrodes induces a radio frequency image charge in the electrodes and an alternating image current in the detection circuit connecting to the electrodes.</item>
