We consider radio-frequency ion guides formed by electrodes, which are periodic sequences of circular apertures. With the help of pulse voltages arranged as trains of a special type, a relay-switched sequence of axial distributions of the pseudopoten

The pseudopotential approach is a useful tool for the qualitative description of ion motion in inhomogeneous high-frequency electric fields, often used in mass spectrometric devices. However, in the theoretical study of the motion of ions in high-fre

An ion-optical design of a new sector field multi-turn time-of-flight analyzer is proposed. The analyzer forms oval-type spiral ion trajectories and possesses second order time-of-flight focusing with respect to both energy and spatial (coordinate an

It is shown that an electrostatic field structure including a local wedge field in the area of small ion kinetic energies, followed by a planar accelerating field, allows to efficiently vary and control the inclination angle of time fronts (isochrono

This paper presents an improved conditioned glow discharge ionization method, based on Penning ionization by metastable argon atoms at fore-vacuum gas pressures. The afterglow flow passes through a capillary to remove charged species (so called “co
