Penning ion trap
Ion trapping device using a static magnetic field and a static electric potential well. The magnetic field confines the ion motion to circular orbits around the magnetic force line direction, which aligns with the direction of the trap axis, whereas the electric potential well confines the ion motion axially.
Note: This device is used for the mass analyzer of Fourier transform-ion cyclotron resonance-mass spectrometers.
