Abstract The theoretical basis of the recently introduced quadrupole detection Fourier transform-ion cyclotron resonance technique is developed by use of the concept of image charges induced in the detection electrodes. The appearance of resonances at frequencies 2ω+, 2ω−, (ω+ + ω−) and (ω+ − ω−) is explained. The new method is compared with the standard (dipole) detection scheme. Techniques are suggested allowing the simultaneous determination of all resonance frequencies ω+ (perturbed, or reduced, cyclotron frequency), ω− (magnetron frequency) and ωz (trapping frequency).
