ABSTRACT:
A vacuum magnetic ion trap includes 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, the convergent and divergent radial magnetized structures (30, 32) being arranged along a common longitudinal axis (XX′) The trap also includes a sealed chamber (4) containing anion confinement cell (8) fixed between the at least two magnetized structures (30, 32) and including at least two trapping electrodes (10) connectable to a voltage generator (12).
