Quadrupole Ion Trap Mass Spectrometer
The quadrupole ion trap is constructed of three electrodes that, when held at appropriate potentials, cause the formation of a trapping pseudo-potential well so that charged particles, or gaseous ions, may be confined or stored for long periods of time. The two end-cap electrodes resemble saucers while the ring electrode resembles a napkin …
Module VI, Lecture 05: Nuclear Quadrupolar Interaction
Because the direction of nuclear quadrupole moment is rigidly connected to the direction of the spin, this electrostatic interaction also manifests it‐ self as a spin interaction, which is effectively quadratic – the spin "interacts with itself":

Understanding Quadrupole Theory
A quadrupole mass filter is composed of four mutually parallel, highly precise, electrically-isolated electrodes. The orientation of the electrodes is such that there is a hyperbolic (quadrupolar) electric field between them. The common quadrupole fabrication technique involves positioning the four round poles in such a fashion that the centers ...
