Abstract

A multi-circumvolant time type mass spectrometer or a Fourier transform type mass spectrometer. A circular orbit (C) satisfying complete time convergence conditions for every unit of semicircle from a point (S, T) to a point (T, S) is formed by four sets of main electrodes (11a, 12a, 13a, 14a). Electrostatic quadrupole lenses (15, 16) consisting of four rod electrodes are arranged in the final free flight space of that unit. Since the potential distribution, in the direction parallel with a plane including a linear ion optical axis, of an electric field formed by the electrostatic quadrupole lenses (15, 16) has such characteristics as becoming an even function with respect to the ion optical axis, ion transmissivity can be enhanced by regulating the polarity or strength of that lens and correcting spatial ion orbit while keeping the time convergence of the circular orbit (C).
