Time‐sharing of electrodes between excitation and detection for Fourier transform (FT) study of the coherent cyclotron motion of ions is discussed, together with the choice of a suitable commutation device. A practical implementation is described, and the application to an open‐end, flat, ion cyclotron resonance cell presented. In addition, the switching technique described is useful to minimise ion losses due to resistive damping at the magnetron frequencies, and could also be used in conventional FT ion cyclotron resonance cells for quadrupolar excitation and detection, and for ion axialization.
