Abstract
A vacuum ion trap includes a gastight processing enclosure and a permanent magnet defining a cavity and creating a directed magnetic field in the cavity, the enclosure being disposed inside the cavity and containing a confinement cell having at least two mutually parallel trapping electrodes perpendicular to the directed magnetic field, the trapping electrodes being connectable to a voltage generator. The trap includes at least one permanent magnet in the form of a hollow cylinder and structured with a Halbach cylinder type structure so as to generate the permanent magnetic field directed perpendicularly to the longitudinal axis of the cavity of the magnet. The trap is applicable in particular to Fourier transform mass spectrometry (FTICR).
