Observation on the Nonlinearity of the Ion-cloud Motion in an RF Trap

In an ion trap with ideal configurations, one single ion moves harmonically under the action of a pure quadrupole potential. The frequency of ion motion can be measured by the use of resonance signals with narrow line width, from which the ionic masses and other fundamental physical constants have b...

Summary:In an ion trap with ideal configurations, one single ion moves harmonically under the action of a pure quadrupole potential. The frequency of ion motion can be measured by the use of resonance signals with narrow line width, from which the ionic masses and other fundamental physical constants have been determined precisely. Usually, the signal broadening, shift and other phenomena related to the nonlinearity of ion motion take place because of the imperfections in fabricating the trap, the in-
