ABSTRACT:
A method of mass spectroscopy according to example embodiments may include injecting ions into a Penning trap and exciting the ions into cyclotron and/or magnetron motions. The cyclotron motions and magnetron motions may be converted to one another with external radio frequency signals. The ions may be ejected from the Penning trap onto a position sensitive charged particle detector to determine the phases and amplitudes of the motions. Ion cyclotron resonance frequencies may be determined based on the phases and amplitudes of the motions of the ejected ions.
