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.
Note: 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.
