In experimental physics, a quadrupole ion trap or paul trap is a type of ion trap that uses dynamic electric fields to trap charged particles. They are also called radio frequency (RF) traps or Paul traps in honor of Wolfgang Paul , who invented the device [ 1 ] [ 2 ] and shared the Nobel Prize in Physics in 1989 for this work. [ 3 ]
A Paul trap is a type of quadrupole ion trap that uses static direct current (DC) and radio frequency (RF) oscillating electric fields to trap ions. Paul traps are commonly used as components of a mass spectrometer. The invention of the 3D quadrupole ion trap itself is attributed to Wolfgang Paul who shared the Nobel Prize in Physics in 1989 ...
Paul trap for the MIRACLS experiment. A Paul trap, also referred to as a quadrupole ion trap or a radio frequency (RF) trap, is an ion trap that uses dynamic electric fields to trap charged particles. It is not possible to create a configuration of static electricity fields to trap the particles in three dimensions, however it is possible with ...
A Penning trap is a device for the storage of charged particles using a homogeneous magnetic field and a quadrupole electric field. It is mostly found in the physical sciences and related fields of study for precision measurements of properties of ions and stable subatomic particles , like for example mass, [ 1 ] fission yields and isomeric ...
Electron transfer dissociation takes place in an ion trap mass spectrometer with an electrospray ionization source. The first ETD experiments at the University of Virginia utilized a radio frequency quadrupole linear ion trap (LQT) modified with a chemical ionization (CI) source at the back side of the instrument (see diagram at right).

A quadrupole electric field is displayed for reference, which oscillates at a given frequency . The blue line represents the ion path in the transversal (or radial) direction of a linear trap, while the orange line is the secular (slow) motion resulting from the ponderomotive force due to the electric field onto the ion.
