Resonance excitation of ions stored in a quadrupole ion trap. Part 1. A simulation study

Preliminary findings are presented of a simulation study of resonance excitation of gaseous ions stored within a quadrupole ion trap. The ion trap was operated in the common mode wherein a radio-frequency drive potential was applied to the ring electrode while the end-cap electrodes were grounded or held at a small potential. The arrangement chosen for computer simulation of resonance excitation discussed here is that in which an auxiliary...
