Abstract:
The invention herein generally relates to non-destructive, high order harmonic ion motion image current detection. In certain embodiments, ion motion corresponding to high order harmonic frequencies, instead of the secular frequencies, is detected using image current detection with a constant excitation applied to the waveform signal.
