The invention concerns a vacuum magnetic ion trap comprising an assembly forming a permanent magnet including at least two magnetized structures (30, 32) in the form of hollow cylinders, one convergent radial structure, magnetized along a convergent radial direction, and one divergent radial structure, magnetized along a divergent radial direction, said convergent and divergent radial magnetized structures (30, 32) being arranged along a common longitudinal axis (XX'). Said trap also comprises a sealed chamber (4) containing an ion confinement cell (8) fixed between said at least two magnetized structures (30, 32) and including at least two trapping electrodes (10) connectable to a voltage generator (12).
Ce piège à ions magnétique sous vide comporte un assemblage formant aimant permanent comprenant au moins deux structures aimantées (30, 32) en forme de cylindres creux, une radiale convergente, aimantée suivant une direction radiale convergente, et une radiale divergente, aimantée suivant une direction radiale divergente, lesdites structures aimantées (30, 32) radiales, convergentes et divergentes étant disposées selon une même axe longitudinal (XX'). Ce piège comporte également une enceinte étanche (4) renfermant une cellule de confinement des ions (8) fixée entre lesdites au moins deux structures aimantées (30, 32) et comprenant au moins deux électrodes de piégeage (10) connectables à un générateur de tension (12).
