Ion trap

An ion trap consists of electrodes that produce electric fields to trap ions, which may be atoms, molecules, or large particles such as dust. Ion traps have a number of applications including mass spe
Charged flour grains held in a Paul ion trap. The grains are glowing under the illumination green light (this does not affect trapping). Their motion during the exposure time is evident in the streaks that the grains made during the photograph.

An Paul ion trap, used for precision measurements of radium ions, inside a vacuum chamber. View ports surrounding the chamber allow laser light to be directed into the trap.

In mass spectrometry, Orbitrap is an ion trap mass analyzer consisting of an outer barrel-like electrode and a coaxial inner spindle-like electrode that traps ions in an orbital motion around the spin
Ion trap
…ω c . An ion trap mass spectrometer may incorporate a Penning trap (Fourier-transform ion cyclotron resonance), Paul trap or the Kingdon trap. The Orbitrap, introduced in 2005, is based on the Kingdon trap. Other types of mass spectrometers may also use a linear quadrupole ion trap as a selective mass…
