Abstract
ICR cells with 2 and 4 mm radius have been characterized. In addition the trapping potential of the 4 mm cells was modified with wire mesh screening electrodes to yield a “particle in a box” potential. It was shown that ions of low m/ z can be trapped. The performance of the cells varies with parameter changes especially at 2 mm cell radius. Peak splitting and mass shifts were observed in spectra of SF 5 +. The results from the 4 mm cells were comparable to those from larger cells with r = 21 mm. Potentials and ion trajectories were simulated with SIMION. The effective cyclotron frequency ω + was calculated by Fourier transformation of simulated transients and shown to depend on the ion's axial coordinate.
