In Section 10.2 is discussed the principal idea of our novel SCSI-MS (Sympathetically-Cooled Single Ion Mass Spectrometry) technique for performing single-ion mass measurements in the light of already well-established techniques. This discussion is followed by both a description of the current experimental arrangement, used for single molecular ion experiments (Section 10.3), and an account of the...

A nondestructive detection technique is often desirable. One such technique is based on the excitation of motional resonances of trapped species. The information about the species is encoded in the frequency of the resonance. This technique has been used in the past for mass spectrometry of ion clouds in the gas or fluid state [29,69]. For a two-ion crystal containing a single molecular ion sympathetically cooled by a single atomic ion, a high mass resolution has been demonstrated [31].
